94e355148f aco: Make sure not to mistakenly propagate 64-bit constants. 
ACO's optimizer would try to propagate 64-bit constants, but
does so in such a way that wouldn't work due to how the 64-bit
constants are handled in the IR.

93c8ebfa78 aco: Initial commit of independent AMD compiler 
ACO (short for AMD Compiler) is a new compiler backend with the goal to replace
LLVM for Radeon hardware for the RADV driver.

ACO currently supports only VS, PS and CS on VI and Vega.
There are some optimizations missing because of unmerged NIR changes
which may decrease performance.
