bcef66fbf3 Fix declaration of loop variables with a Phi helper copy.
Certain Phi variables need to maintain a temporary copy, but we forgot
to declare them when the master variable is a loop variable itself.

65af09d2d1 Support emitting OpLine directive.
Facilitates easier mapping from source language to cross-compiled output
in tooling.

317144a59c Detect invalid DoWhileLoop early.
We had a bug where error conditions in DoWhileLoop emit path would not
detect that statements were being emitted due to the masking behavior
which happens when force_recompile is true. Fix this.

Also, refactor force_recompile into member functions so we can properly
break on any situation where this is set, without having to rely on
watchpoints in debuggers.

2a0365c813 GLSL/HLSL: Implement NMin/NMax/NClamp.

0b20180537 GLSL: Deal with array loads from input in tessellation.
We have an edge case where the array is declared with a concrete size,
but in GLSL we must emit an unsized array, which breaks array copies.
Deal explicitly with this.

a4ac27546a MSL: Fix textures which are sampled and compared against.
depth2d in MSL only returns float, not float4, even for normal sampling.
We need to conditionally remap-swizzle back to float4.

d7090b8322 GLSL: Fix block name shenanigans in edge cases.
When we force recompile, the old var.self name we used as a fallback
name might have been disturbed, so we should recover certain names back
to their original form in case we are forced to take a recompile to make
the naming algorithm more deterministic.

9728f9c1b7 Use correct block-name / other-name aliasing rules.
A block name cannot alias with any name in its own scope,
and it cannot alias with any other "global" name.

To solve this, we need to complicate the name cache updates a little bit
where we have a "primary" namespace and "secondary" namespace.

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.

3b5968bb26 Deal with switch cases which break out of a loop.
Need some pretty hideous ladder variable system, but high level
languages do not support breaking out of a loop. break in switch blocks
and break in loops alias each other.

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.

361fe52c9d MSL: Properly support passing parameters by value.
MSL would force thread const& which would not work if the input argument
came from a different storage class.

Emit proper non-reference arguments for such values.
