3e584f2c3f Support LUTs in single-function CFGs on Private storage class. 
Fairly common pattern in unoptimized SPIR-V. Support this case as well.

acae607703 Register implied expression reads in OpLoad/OpAccessChain. 
This is required to avoid relying on complex sub-expression elimination
in compilers, and generates cleaner code.

The problem case is if a complex expression is used in an access chain,
like:

Composite comp = buffer[texture(...)];
vec4 a = comp.a + comp.b + comp.c;

Before, we did not have common subexpression tracking for
OpLoad/OpAccessChain, so we easily ended up with code like:

vec4 a = buffer[texture(...)].a + buffer[texture(...)].b + buffer[texture(...)].c;

A good compiler will optimize this, but we should not rely on it, and
forcing texture(...) to a temporary also looks better.

The solution is to add a vector "implied_expression_reads", which works
similarly to expression_dependencies. We also need an extra mechanism in
to_expression which lets us skip expression read checking and do it
later. E.g. for expr -> access chain -> load, we should only trigger
a read of expr when using the loaded expression.

226d837d7e HLSL: Use same logic as GLSL for picking cbuffer block name. 
HLSL just picked the variable name which did not work as expected for
some users. Use the same logic as GLSL and set up declared_block_names,
so the actual name can be queried later.

af75ef005f Update glslang and SPIRV-Tools. 
A lot of changes in spirv-opt output.
Some new invalid SPIR-V was found but most of them were not significant
for SPIRV-Cross, so just marked them as invalid.

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

1f16f0d260 Use 'static const' for spec constants in HLSL 
If 'const' is used, the shader expects the variable to be backed by a
constant buffer. 'static const' is probably preferred for a value that
is initialized with a constant in the HLSL source code.

FXC also emits a warning for 'const' variables with initializers, since
'static const' was probably intended.
