Matt Arsenault 0ed39d329d AMDGPU: Partially fix improper reliance on memoperands 
There are 2 more places doing this, but I'm not sure
what they are doing and don't make any sense to me

Mark Searles 11d0a04050 [AMDGPU] Fix bugs in new waitcnt pass. Add test. 
- new waitcnt pass remains off by default; -enable-si-insert-waitcnts=1 to enable it
- fix handling of PERMUTE ops
- fix insertion of waitcnt instrs at function begin/end ( port of analogous code that was added to old waitcnt pass )
- add new test

Kannan Narayanan 5e73b04b84 [AMDGPU] In the new waitcnt insertion pass, use getHeader 
instead of getTopBlock to find the loop header.

Krzysztof Parzyszek 44e25f37ae Move size and alignment information of regclass to TargetRegisterInfo 
1. RegisterClass::getSize() is split into two functions:
   - TargetRegisterInfo::getRegSizeInBits(const TargetRegisterClass &RC) const;
   - TargetRegisterInfo::getSpillSize(const TargetRegisterClass &RC) const;
2. RegisterClass::getAlignment() is replaced by:
   - TargetRegisterInfo::getSpillAlignment(const TargetRegisterClass &RC) const;

This will allow making those values depend on subtarget features in the
future.
