24f019fd69 spirv: Allow ignoring decorations for workgroup variables
Since we switched over to lowering SLM access directly in SPIR-V -> NIR,
we no longer have vtn_variables for SLM.  It's all safe as with UBOs and
SSBOs but we need to let it through in the assert.

7cf1037d5a main, glsl: Add UniformDataDefaults which stores uniform defaults
The ARB_get_program_binary extension requires that uniform values in a
program be restored to their initial value just after linking.

This patch saves off the initial values just after linking. When the
program is restored by glProgramBinary, we can use this to copy the
initial value of uniforms into UniformDataSlots.

V2 (Timothy Arceri):
 - Store UniformDataDefaults only when serializing GLSL as this
   is what we want for both disk cache and ARB_get_program_binary.
   This saves us having to come back later and reset the Uniforms
   on program binary restores.

59f458cd87 glsl: Add 16-bit types
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.

93b4cb61eb spirv: Allow OpPtrAccessChain for block indices
The SPIR-V spec is a bit underspecified when it comes to exactly how
you're allowed to use OpPtrAccessChain and what it means in certain edge
cases.  In particular, what if the base pointer of the OpPtrAccessChain
points to the base struct of an SSBO instead of an element in that SSBO.
The original variable pointers implementation in mesa assumed that you
weren't allowed to do an OpPtrAccessChain that adjusted the block index
and asserted such.  However, there are some CTS tests that do this and,
if the CTS does it, someone will do it in the wild so we should probably
handle it.  With this commit, we significantly reduce our assumptions
and should be able to handle more-or-less anything.

The one assumption we still make for correctness is that if we see an
OpPtrAccessChain on a pointer to a struct decorated block that the block
index should be adjusted.  In theory, someone could try to put an array
stride on such a pointer and try to make the SSBO an implicit array of
the base struct and we would not give them what they want.  That said,
any index other than 0 would count as an out-of-bounds access which is
invalid.

ae54a4f84f spirv: Add support for lowering workgroup access to offsets
Before, we always left workgroup variables as shared nir_variables and
let the driver call nir_lower_io.  This adds an option to do the
lowering directly in spirv_to_nir.  To do this, we implicitly assign the
variables a std430 layout and then treat them like a UBO or SSBO and
immediately lower all the way to an offset.

As a side-effect, the spirv_to_nir pass now handles variable pointers
for workgroup variables.

94ca8e04ad spirv: Add vtn_fail and vtn_assert helpers
These helpers are much nicer than just using assert because they don't
kill your process.  Instead, it longjmps back to spirv_to_nir(), cleans
up all the temporary memory, and nicely returns NULL.  While crashing is
completely OK in the Vulkan world, it's not considered to be quite so
nice in GL.  This should help us to make SPIR-V parsing much more
robust.  The one downside here is that vtn_assert is not compiled out in
release builds like assert() is so it isn't free.

However, previously, the function could be called if an non-array
interface block has different type definitions -for example, when the
precision qualifier differs in a GLSL ES shader, we would create two

non-arrays.

We fix this by specifying that at least one definition should be an
array to call the validation.
