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.

Simon Pilgrim 4003ed2da3 [DAGCombiner] Improve FMA support for interpolation patterns 
This patch adds support for combining patterns such as (FMUL(FADD(1.0, x), y)) and (FMUL(FSUB(x, 1.0), y)) to their FMA equivalents.

This is useful in particular for linear interpolation cases such as (FADD(FMUL(x, t), FMUL(y, FSUB(1.0, t))))
