Stanislav Mekhanoshin 196e7f3138 [AMDGPU] Use single cache policy operand 
Replace individual operands GLC, SLC, and DLC with a single cache_policy
bitmask operand. This will reduce the number of operands in MIR and I hope
the amount of code. These operands are mostly 0 anyway.

Additional advantage that parser will accept these flags in any order unlike
now.
