Timur Kristóf	d59f702e26	aco: Implement subgroup shuffle in GFX10 wave64 mode. ... Previously subgroup shuffle was implemented using the bpermute instruction, which only works accross half-waves, so by itself it's not suitable for implementing subgroup shuffle when the shader is running in wave64 mode. This commit adds a trick using shared VGPRs that allows to implement subgroup shuffle still relatively effectively in this mode.

Daniel Schürmann	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.
