It was missing when there were no semantics.

Added getter for uniform block bindings

Non-Functional: Remove unused parts of the disassembler.

Implement GL_NV_shader_subgroup_partitioned

Only print legalization warning if optimizer not enabled

Array rationalization

Disable DCE by Remapper through glslangValidator...

Add int16 support to AMD_trinary_minmax and AMD_shader_ballot

- Use much simpler method to update implicit array sizes.
  The previous overly complicated method was error prone.
- Rationalize all use of unsized arrays.
- Combine decorations when generating SPIR-V, to simplify
  adding extensions.

...now that spirv-opt is capable enough.

Update SPIRV-Tools known good.

Fix mixed array styles

Also update spirv-opt recipes.

There a couple functional problems, which when reduced down also led to
some good simplifications and rationalization.  So, this commit:
 - corrects "mixed" functionality: int[A] f[B] -> f[B][A]
 - correct multi-identifier decls: int[A] f[B], g[C] -> f and g are independently sized.
 - increases symmetry between different places in the code that do this
 - makes fewer ways to do the same thing; several methods are just gone now
 - makes more clear when something is copied or shared

This effects 60 tests, in a trivial way, but is critical to factor out this
noise from future planned changes.

Fixes #1304.

Should fix #1308.

Improve --auto-map-locations for uniforms (v2)

Add additional error check for fragment shader outputs

When assigning uniform locations it now takes into account the number
of locations occupied by the type. For uniforms, all types except
arrays and structs take up one location. For arrays the base location
count is multiplied by the array dimensions and for structs it is the
sum of the locations of each member.
