    Revert "ir_to_mesa: Load all the STATE_VAR elements of a builtin uniform to a temp."
    
    This reverts commit 5ad74779cea07cc6a19a52874cdaef8b018e2f1b.
    
    Sorry, but I had to revert this.
    
    Any commit which needlessly increases the number of temporaries is wrong.
    More temporaries mean less shader performance because of reduced parallelism
    and therefore less efficient latency hiding. In this case, there is possible
    performance degradation of every shader which uses GL state variables.
    I cannot accept this.

    r300/compiler: improve register allocation with indexable temporaries for VS
    
    Register allocation can now reallocate temporaries right after the last indexed
    source operand, instead of being disabled for the whole shader.

    r300g: add a new debug option which disables compiler optimizations
    
    Those are:
    - dead-code elimination
    - constant folding
    - peephole (mainly copy propagation)
    - register allocation
    
    There are some bugs which I need to track down.
    
    Also fix up the descriptions of all the debug options.

    r300/compiler: compute the final number of temporaries during translation
    
    And not during the register allocation, which may be skipped for debugging
    purposes. Also the predicate register is now added to the number of temps.

    r300/compiler: refactor vertex shader compilation
    
    First list compiler passes in an array, then run the new function rc_run_compiler.
    Every backend may need a different set of passes.
    This cleans up the mess in r3xx_compile_vertex_program.

    r300/compiler: use null-terminated array of transformation functions
    
    I need to reduce the number of parameters of each compiler pass function.
    This is part of a larger cleanup.
