  -----------
  [AMDGPU] Group multiple single use producers under one single use instruction. (#90713)

Previously each single use producer would be marked with a
"S_SINGLEUSE_VDST 1" instruction. This patch adds support for
larger immediates that encode multiple single use producers into
one S_SINGLEUSE_VDST instruction.
