Adding `nir_rematerialize_derefs_in_use_blocks_impl`
solves some cases when 'opt_dead_cf()' generates
a phi instruction for the first argument
of the `deref_store` intrinsic.

Use the string itself as a key for searching -- and the internal
allocated name as a key when storing.
Because record_key_hash doesn't consider the name field, which is
the only used field for a SUBROUTINE type, the hash key was always
the same for all types. Using the name fixes this.

For VK_KHR_fragment_shader_barycentric, AMD needs to know the primitive
topology in the fragment shader but with fast-link GPL this is unknown
at compile time and it needs to be passed dynamically.

In many cases the raw value is not really helpful,
since we only work with enums and the raw value is
already printed for indices without special printing.
If an index benefits from having special printing AND the
raw value, we can include the printing of the raw value
as part of its handler.

The DXIL backend would like to distinguish between casts to 16-bit
that must cast, vs those that may. If a shader only ever produces
16-bit types from mediump casts and ALU ops on those values, then
the resulting shader can be annotated with DXIL's min-precision
qualifier, basically telling the driver to use 16-bit precision if
it's faster for them. If it uses concrete 16-bit casts, or loads/
stores to externally-visible memory, then it must use the "native"
16-bit flag, which is not supported on all hardware.
