1fb27b4cda Add support for 8- and 16-bit types to GLSL and MSL.
In GLSL, 8-bit types require GL_EXT_shader_8bit_storage. 16-bit types
can use either GL_AMD_gpu_shader_int16/GL_AMD_gpu_shader_half_float or
GL_EXT_shader_16bit_storage.

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.

146ea76f52 Add test shader for subgroup.
Update SPIRV-Tools/glslang commits.
Use vulkan1.1 environment for testing.
Found new "errors" in SPIRV-Tools, so disable validation on those shaders
for now.

dd603eab58 Support spec constant array size in blocks.
Won't really be correct if the spec constant is changed outside
SPIRV-Cross, but nothing we can do about that, really.
