480acdad18 Deal with OpSpecConstantOp used as array size.
When trying to validate buffer sizes, we usually need to bail out when
using SpecConstantOps, but for some very specific cases where we allow
unsized arrays currently, we can safely allow "unknown" sized arrays as
well.

This is probably the best we can do, when we have even more difficult
cases than this, we throw a more sensible error message.

a5d82d1138 Alter the handling of spec consts in non-Vulkan GLSL
Previously, when generating non-Vulkan GLSL, each use of a spec constant
would be subsituted for its default value and the declaration of the constant
itself would be omitted completely.

This change slightly alters this behavior. The uses of the constant are kept,
as well as the declaration, although the latter is stripped of the layout
qualifier. The declaration is also prepended with the following code:

    #ifndef <constant name>_value
    #define <constant name> <default constant value>
    #endif

and the constant itself now looks like

    const <constant type> <constant name> = <constant name>_value;

The rationale for this change is that it gives the user a way to provide
custom values for specialization constants even when the target does not
support them.

7f055e8a68 Fix Options::force_temporary to work with OpenGL GLSL
Setting force_temporary to true produces invalid GLSL because sampler
variables are copied:

    highp sampler2D _377 = DiffuseMapTexture;

This change fixes the problem by always forwarding forwardable
variables. I also took an opportunity to restructure the code to make
it easier to read and add extra conditions to in the future.

5bcf02f7c9 Hoist out parsing module from spirv_cross::Compiler.
This is a large refactor which splits out the SPIR-V parser from
Compiler and moves it into its more appropriately named Parser module.

The Parser is responsible for building a ParsedIR structure which is
then consumed by one or more compilers.

Compiler can take a ParsedIR by value or move reference. This should
allow for optimal case for both multiple compilations and single
compilation scenarios.

3a9af9681c MSL: Expand arrays of buffers passed as input.
Even as of Metal 2.1, MSL still doesn't support arrays of buffers
directly. Therefore, we must manually expand them. In the prologue, we
define arrays holding the argument pointers; these arrays are what the
transpiled code ends up referencing. We might be able to do similar
things for textures and samplers prior to MSL 2.0.

Speaking of which, also enable texture arrays on iOS MSL 1.2.

d310060f92 MSL: Support global I/O block and struct Input/Output usage.
Implement this by flattening outputs and unflattening inputs explicitly.
This allows us to pass down a single struct instead of dealing with the
insanity that would be passing down each flattened member separately.

Remove stage_uniforms_var_id.
Seems to be dead code. Naked uniforms do not exist in SPIR-V for Vulkan,
which this seems to have been intended for. It was also unused elsewhere.

87de951105 MSL: Fix naming issue of aliased global variables.
When the name of an alias global variable collides with a global
declaration, MSL would emit inconsistent names, sometimes with the
naming fix, sometimes without, because names were being tracked in two
separate meta blocks. Fix this by always redirecting parameter naming to
the original base variable as necessary.

91fd41816f Fix textureGrad compilation for legacy targets
textureGrad isn't part of core GL2 or GLES2. In desktop GL, it's

d4e470babd Analyze the CFG for temporaries as well.
Normally, temporary declaration must dominate any use of it,
so we generally did not need to analyze the CFG for these variables,
but there is an edge case where you have an inliner doing:

do {
	create_temporary;
	break;
} while(0);

use_temporary;

The inside of the loop dominates the outer scope, but we cannot emit
code like this in GLSL, so make sure we hoist these temporaries outside
the "loop".
