Subject: [PATCH 1/2] [AMDGPU] Deallocate VGPRs before exiting in dynamic VGPR
mode
In dynamic VGPR mode, Waves must deallocate all VGPRs before exiting. If
the shader program does not do this, hardware inserts `S_ALLOC_VGPR 0`
before S_ENDPGM, but this may incur some performance cost. Therefore
it's better if the compiler proactively generates that instruction.
This patch extends `si-insert-waitcnts` to deallocate the VGPRs via
a `S_ALLOC_VGPR 0` before any `S_ENDPGM` when in dynamic VGPR mode.
