nir/algebraic: Only replace an instruction once
Without the break, it was possible that an instruction would match multiple
expressions. If this happened, you could end up trying to replace it
multiple times and get a segfault. This makes it so that, after a
successful replacement, it moves on to the next instruction.

This refactor allows you to more easily get the deref node associated with
a given variable. We then use that new functionality in the
deref_may_be_aliased function instead of creating a 1-element deref chain.

This solves a number of problems. First is the ability to change the
number of sources that a texture instruction has. Second, it solves the
delema that may occur if a texture instruction has more than 4 sources.

This was a left-over relic of GLSL IR that we aren't using for anything.
If we ever want that value again, we can add it back, but NIR constant
folding should be just as good as GLSL IR's if not better pretty soon, so
I'm not worried about it.

nir/lower_variables: Follow the Cytron paper more closely
Previously, our variable renaming algorithm, while similar to the one in
the Cytron paper, was not the same. While I'm pretty sure it was correct,
it will be easier for readers of the code in the variable renaming pass if
it follows more closely. This commit removes the automatic stack popping
we were doing and replaces it with explicit popping like Cytron does.

nir: Rename parallel_copy_copy to parallel_copy_entry and add a foreach macro
parallel_copy_copy was a silly name. Also, things were getting long and
annoying, so I added a foreach macro. For historical reasons, several of
the original iterations over parallel copy entries in from_ssa used the
_safe variants of the loop. However, all of these no longer ever remove an
entry so it's ok to make them all use the normal iterator.

nir/from_ssa: Clean up parallel copy handling and document it better
Previously, we were doing a lazy creation of the parallel copy
instructions. This is confusing, hard to get right, and involves some
extra state tracking of the copies. This commit adds an extra walk over
the basic blocks to add the block-end parallel copies up front. This
should be much less confusing and, consequently, easier to get right. This
commit also adds more comments about parallel copies to help explain what
all is going on.
As a consequence of these changes, we can now remove the at_end parameter
from nir_parallel_copy_instr.

later on. When it comes time for setting up VS, we can put setup for its

nir/opcodes: Remove the per_component info field
Originally, this field was intended for determining if the given
instruction acted per-component or if it had mismatching source and
destination sizes that would have to be interpreted specially. However, we
can easily derive this from output_size == 0, so it's not really that
useful. Also, the values we were setting in nir_opcodes.h for this field
were completely bogus and it was never used.

nir/opcodes: Add algebraic properties metadata
This commit adds some algebraic properties to the metadata of each opcode
in NIR. In particular, you now know, just from the metadata, if a given
opcode is commutative or associative. This will be useful for algebraic
transformation passes that want to be able to match a + b as well as b + a
in one go.
v2: Make algebraic properties all caps. This was more consistent with the
intrinsics flags and seems better for flags in general.
Also, the enums are now declared with (1 << n) rather then hex values.
v3: fmin and fmax technically aren't commutative or associative. Things
get funny when one of the arguments is a NaN.

nir: Use nir_foreach_ssa_def for setting up ssa destinations
Before, we were using foreach_dest and switching on whether the destination

so we have to special-case ssa_undef instructions. Now that we have a
foreach_ssa_def function, we can iterate over all of the register
destinations in one pass and iterate over the SSA destinations in a second.
This way, if we add other ssa-only instructions, we won't have to worry
about adding them to the special case we have for ssa_undef.

Previously, we were just iterating over the program "in order" which

loop {

} else {
break;

where use(a) would get 3 instead of 5 because of premature popping of the
SSA def stack. Now, since we do an actaul DFS, we should evaluate use(a)
immediately after a = 5 and we should be ok.

nir: Use a source for uniform buffer indices instead of an index
In GLSL-to-NIR we were just setting the base index to 0 whenever there was
an indirect so having it expressed as a sum makes no sense. Also, while a
base offset may make sense for the memory location (first element in the
array, etc.) it makes less sense for the actual uniform buffer index. This
may change later, but it seems to make more sense for now.

nir: Add infastructure for generating algebraic transformation passes
This commit builds on the nir_search.h infastructure by adding a bit of
python code that makes it stupid easy to write an algebraic transformation
pass. The nir_algebraic.py file contains four python classes that
correspond directly to the datastructures in nir_search.c and allow you to
easily generate the C code to represent them. Given a list of
search-and-replace operations, it can then generate a function that applies
those transformations to a shader.
The transformations can be specified manually, or they can be specified
using nested tuples. The nested tuples make a neat little language for
specifying expression trees and search-and-replace operations in a very
readable and easy-to-edit fasion.
The generated code is also fairly efficient. Insteady of blindly calling
nir_replace_instr with every single transformation and on every single
instruction, it uses a switch statement on the instruction opcode to do a
first-order culling and only calls nir_replace_instr if the opcode is known
to match the first opcode in the search expression.

nir: Add an expression matching framework
This framework provides a simple way to do simple search-and-replace
operations on NIR code. The nir_search.h header provides four simple data
structures for representing expressions: nir_value and four subtypes:
nir_variable, nir_constant, and nir_expression. An expression tree can
then be represented by nesting these data structures as needed. The
nir_replace_instr function takes an instruction, an expression, and a
value; if the instruction matches the expression, it is replaced with a new
chain of instructions to generate the given replacement value. The
framework keeps track of swizzles on sources and automatically generates
the currect swizzles for the replacement value.

nir: Make the type casting operations static inline functions
Previously, the casting operations were macros. While this is usually
fine, the casting macro used the input parameter twice leading to strange
behavior when you passed the result of another function into it. Since we
know the source and destination types explicitly, we don't loose anything
by making it a function.
Also, this gives us a nice little macro for creating cast function that
will hopefully prevent mistyping.

nir/nir: Fix a bug in move_successors
The unlink_blocks function moves successors around to make sure that, if
there is a remaining successor, it is in the first successors slot and not
the second. To fix this, we simply get both successors up front.

nir: Differentiate between signed and unsigned versions of find_msb
We also make the return types match GLSL. The GLSL spec specifies that
findMSB and findLSB return a signed integer. Previously, nir had them
return unsigned. This updates nir's behavior to match what GLSL expects.
We also update the nir-to-fs generator to take the new instructions. While
we're at it, we fix the case where the input to findMSB is zero.
