AMDGPU: Legalize the operand of SI_INIT_M0 Summary: This fixes a case where the argument to a sendmsg intrinsic ends up in a VGPR, for whatever reason. The underlying performance issue is that a multiplication that can be an s_mul_i32 is instead needlessly generated as v_mul_u32_u24, but this is not addressed by this patch.

AMDGPU: Force skip over s_sendmsg and exp instructions Summary: These instructions interact with hardware blocks outside the shader core, and they can have "scalar" side effects even when EXEC = 0. We don't want these scalar side effects to occur when all lanes want to skip these instructions, so always add the execz skip branch instruction for basic blocks that contain them. Also ensure that we skip scalar stores / atomics, though we don't code-gen those yet.
