Update intrinsics to use n x f16 and n x i16 instead
of 32-bit types. This may avoid the need for a bitcast
and is probably less confusing.
Depends on making v16f16 and v16i16 types legal.

GFX11 has a new message type MSG_DEALLOC_VGPRS which can be used to
release a shader's VGPRs. Sending this at the end of a shader (just
before the s_endpgm) can help overall system performance in cases where
the s_endpgm would have to wait for outstanding VMEM stores to complete
before releasing the VGPRs.
