Matt Arsenault 3d1c1deb04 AMDGPU: Run SIFoldOperands after PeepholeOptimizer
PeepholeOptimizer cleans up redundant copies, which makes
the operand folding more effective.

Matt Arsenault 44e5483ada AMDGPU: Add volatile to test loads and stores
When the memory vectorizer is enabled, these tests break.
These tests don't really care about the memory instructions,
and it's easier to write check lines with the unmerged loads.

Nikolay Haustov 6560781c4f [AMDGPU] Assembler: change v_madmk operands to have same order as mad.
The constant is now at source operand 1 (previously at 2).
This is also how it is in legacy AMD sp3 assembler.
Update tests.

Tom Stellard db5a11f698 AMDGPU/SI: Select mad patterns to v_mac_f32
The two-address instruction pass will convert these back to v_mad_f32
if necessary.
