ARB_gl_spirv adds the ability to use SPIR-V binaries, and a new
method, glSpecializeShader. Here we add a new function to do the
validation for this function:
From OpenGL 4.6 spec, section 7.2.1"
"Shader Specialization", error table:
INVALID_VALUE is generated if <pEntryPoint> does not name a valid
entry point for <shader>.
INVALID_VALUE is generated if any element of <pConstantIndex>
refers to a specialization constant that does not exist in the
shader module contained in <shader>.""
v2: rebase update (spirv_to_nir options added, changes on the warning
logging, and others)
v3: include passing options on common initialization, doesn't call
setjmp on common_initialization
v4: (after Jason comments):
* Rename common_initialization to vtn_builder_create
* Move validation method and their helpers to own source file.
* Create own handle_constant_decoration_cb instead of reuse existing one
v5: put vtn_build_create refactoring to their own patch (Jason)
v6: update after vtn_builder_create method renamed, add explanatory
comment, tweak existing comment and commit message (Timothy)
