This is needed for future patch. It is possible to allocate all
VGPRs and use MFMA with VGPRs if we have less then 257 registers
and have no calls, but we need to make sure AGPRs are not used
by an inline asm. It is done as an annotation because the way to
use MFMA with VGPRs is to select a proper opcode, so it shall be
known by the time of selection.
