Adds new INT16, UINT16 and FLOAT16 base types.
The corresponding GL types for half floats were reused from the
AMD_gpu_shader_half_float extension. The int16 and uint16 types come from
NV_gpu_shader_5 extension.
This adds the builtins and the lexer support.
To avoid a bunch of warnings due to cases not handled in switch, the
new types have been added to a few places using same behavior as
their 32-bit counterparts, except for a few trivial cases where they are
already handled properly. Subsequent patches in this set will provide
correct 16-bit implementations when needed.
v2: * Use FLOAT16 instead of HALF_FLOAT as name of the base type.
* Removed float16_t from builtin types.
* Don't copy 16-bit types as if they were 32-bit values in
copy_constant_to_storage().
* Use get_scalar_type() instead of adding a new custom switch
statement.
(Jason Ekstrand)
v3: Use GL_FLOAT16_NV instead of GL_HALF_FLOAT for consistency
(Ilia Mirkin)
v4: Add missing 16-bit base types support in glsl_to_nir (Eduardo Lima).
v5: Fix coding style (Topi Poholainen).

There was no reason to treat array types and record types differently.
Unifying them saves a bunch of code and saves a few bytes in every
ir_constant.

The next patch will unify ::array_elements and ::components, so the
name ::array_elements wouldn't be appropriate. A lot of things use
the names array_elements and components, so grepping for either is
pretty useless.

We are currently copying the name for each member dereference
but we can just share a single instance of the string provided
by the type.
This change also stops us recalculating the field index
repeatedly.

Extra validation is added to ir_validate to make sure this is
always updated to the correct numer of operands, as passes like
lower_instructions modify the instructions directly rather then
generating a new one.
The reduction in time is so small that it is not really
measurable. However callgrind was reporting this function as
being called just under 34 million times while compiling the
Deus Ex shaders (just pre-linking was profiled) with 0.20%
spent in this function.
v2:
- make num_operands a unit8_t
- fix unsigned/signed mismatches

From section 5.4.1 of the ARB_bindless_texture spec:
"In the following four constructors, the low 32 bits of the
sampler type correspond to the .x component of the uvec2 and
the high 32 bits correspond to the .y component."
uvec2(any sampler type) // Converts a sampler type to a
// pair of 32-bit unsigned integers
any sampler type(uvec2) // Converts a pair of 32-bit unsigned integers to
// a sampler type
uvec2(any image type) // Converts an image type to a
// pair of 32-bit unsigned integers
any image type(uvec2) // Converts a pair of 32-bit unsigned integers to
// an image type
v4: - fix up comment style
v3: - rebase (and remove (sampler) ? 1 : vector_elements)

This adds the builtins and the lexer support.
To avoid too many warnings, it adds basic support to the type in a few
other places in mesa, mostly in the trivial places.
It also adds a query to be used later for if a type is an integer 32 or 64.

I do appreciate the cleverness, but unfortunately it prevents a lot more
cleverness in the form of additional compiler optimizations brought on
by -fstrict-aliasing.
No difference in OglBatch7 (n=20).

This fixes a bug that breaks cull distances. The problem
is the max array accessors can't tell the difference between
an never accessed unsized array and an accessed at location 0
unsized array. This leads to converting an undeclared unused
gl_ClipDistance inside or outside gl_PerVertex to a size 1
array. However we need to the number of active clip distances
to work out the starting point for the cull distances, and
this offset by one when it's not being used isn't possible
to distinguish from the case were only the first element is
accessed. I tried to use ->used for this, but that doesn't
work when gl_ClipDistance is part of an interface block.
So this changes things so that max_array_access is an int
and initialised to -1. This also allows unsized arrays to
proceed further than that could before, but we really shouldn't
mind as they will get eliminated if nothing uses them later.
For initialised uniforms we no longer change their array
size at runtime, if these are unused they will get eliminated
eventually.
v2: use ralloc_array (Ilia)

SPIR-V has a concept of a function type that's used fairly heavily. We
could special-case function types in SPIR-V -> NIR but it's easier if we
just add support to glsl_types.
