05bb745d - [AMDGPU] Fix regclass for a true16 pattern. NFCI. (#206513)

[AMDGPU] Fix regclass for a true16 pattern. NFCI. (#206513) Add an EXTRACT_SUBREG to make it clear that the result of the pattern is only the low 16 bits of the result of the V_BFI_B32. This does not seem to affect codegen, presumably because we are lax about allowing COPY between VGPR_16 and VGPR_32.
