freedreno: a2xx: ir2 update

this patch brings a number of changes to ir2:
-ir2 now generates CF clauses as necessary during assembly. this simplifies
 fd2_program/fd2_compiler and is necessary to implement optimization passes
-ir2 now has separate vector/scalar instructions. this will make it easier
 to implementing scheduling of scalar+vector instructions together. dst_reg
 is also now seperate from src registers instead of a single list
-ir2 now implements register allocation. this makes it possible to compile
 shaders which have more than 64 TGSI registers
-ir2 now implements the following optimizations: removal of IN/OUT MOV
 instructions generated by TGSI and removal of unused instructions when
 some exports are disabled
-ir2 now allows full 8-bit index for constants
-ir2_alloc no longer allocates 4 times too many bytes
