  -----------
  [AMDGPU][CodeGen] Place `S_NOP` after `S_SETREG_IMM32_B32` in predecessor MBB (#209620)

When placing a `S_SET_VGPR_MSB` at the beginning of a block, check
whether there exists a `S_SETREG_IMM32_B32(MODE)` in the predecessor
block that falls-through into it; if there is one a `S_NOP` has to be
inserted in between them.
