These will let us make the SDWA optimizer much simpler than if we were to
recognize combinations of shift/and/bfe.

clang generates a warning if there's no explicit break or fall-through
annotation. The latter would be kind of silly in this case, and not
robust against any future changes turning the fall-through invalid.

This patch delays the calculation of GPR limits in order to
precisely incorporate extra registers (VCC etc.) and shared VGPRs.
Additionally, the allocation granularity is used to set the config.
This has some effect on the reported SGPR stats.

We can copy any value into a 16-bit subregister with a 3 dword
v_pack_b32_f16 on GFX10 or a v_and_b32+v_or_b32 on GFX9.
Because the generated code can depend on the register assignment and to
improve constant propagation, Builder::copy creates a p_create_vector in
the case of sub-dword literals.
