For unmerged shaders on GFX9+, we would need to jump to the second
shader part which means shared VGPRs can't be enabled.

The vulkan spec says all conversions are correctly rounded, so if the input
is larger than the largest fp16 value, we need to return MAX_FLOAT/inf
instead of cutting off the msbs.

On GFX9+, VS is merged with TCS which means this function is called
twice and the epilog was emitted in both shader parts.

For radeonsi to relocation const data when combine multiple
shader parts to a single one. So the final shader binary will
begin with exec code of all parts then const data.

TCS may be wrapped with if/else when merged shader. Jump
to epilog or end with regs should not be inside it.

The names basically had the same meaning. Changing them to
uniform_shader_addr and shader_addr makes it clear, that
uniform_shader_addr is the jump target and shader_addr is the next
shader executed by this invocation.
The next_ prefix is dropped since both are input and output variables.

Instead, we replace it directly with nir_def. We could replace it with
nir_dest but the next commit gets rid of that so this avoids unnecessary
churn. Most of this commit was generated by sed:
sed -i -e 's/dest.dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp
There were a few manual fixups required in the nir_legacy.c and
nir_from_ssa.c as nir_legacy_reg and nir_parallel_copy_entry both have a
similar pattern.

The SPIR-V spec says:
If Value is positive with a magnitude too large to represent as a
16-bit floating-point value, the result is positive infinity.
If Value is negative with a magnitude too large to represent as a
16-bit floating-point value, the result is negative infinity.
This is only the case for rtne v_cvt_f16_f32

If you are unhappy that I did not manually change the whitespace of your driver,
you need to enable clang-format for it so the formatting would happen
automatically.
