8fe0e6eb01 [DAG] Remove isVectorClearMaskLegal() check from vector_build dagcombine 
This check currently doesn't seem to do anything useful on any in-tree target:
On non-x86, it always evaluates to false, so we never hit the code path that
creates the shuffle with zero.
On x86, it just forwards to isShuffleMaskLegal(), which is a reasonable thing to
query in general, but doesn't make sense if only restricted to zero blends.

69b2d0adeb AMDGPU: Add a shader calling convention 
This makes it possible to distinguish between mesa shaders
and other kernels even in the presence of compute shaders.
