eee9d536bc Track separate entry-point names and mangled names... 
... and use each in the correct way at consumption sites.
This completes issue #513.

55717302ef Refactor TLiveTraverser from the former reflection traverser, for future use in binding mapping. 
This PR factors out the code that knows how to walk just the live parts of the AST.
The traverser in reflect.cpp is renamed to TReflectionTraverser, and inherits from
TLiveTraverser, which will also be used by a future binding offset PR.

The code is now smart about the entry point name (no longer hardcoded to "main").

There is an option to traverse all code (live+dead), because a consumer of the
class may wish to use it for both purposes without wanting a whole separate
class hierarchy.

f8e494c18c HLSL: Flatten all input/output structs, regardless of stage. 
This is needed because an output structure can contain embedded built-ins
(like SV_Position) which should not get locations assigned.

7dc630f3da HLSL: Flatten a return struct from an entry point and assign locations after flattening. 
Locations now get assigned in order, but skipping built-ins, which can be
done post flattening.

7735b94403 HLSL Non-Functional: Move to more robust capturing of postDecls into a qualifier. 
This will prevent a possible future defect of thinking the type can be changed,
where there is a code path today that would drop that change.

4bf7155051 SPV: Flatten structs for copy when they are GLSL type aliases. 
Addresses issue #304 and issue #307 by replacing unmatched type OpStores with
per-member copies. Covers assignment statements and most argument passing, but
does not yet cover r-value-based argument passing.

f2b7f3353b SPV: Tighten up number of struct-types declared based on decoration. 
Takes some pressure off of issue #304.
Structures don't inherit locations and then explicitly decorate
members with them, so removed this reason to have another instance
of a structure type.

5e56423046 Front-ends: Remove now defunct afterEOF and related, use scanner's instead. 
Code using atEndOfFile was dead, instead do something useful with
the scanners atEndOfInput().  This allows a better error message
for early termination of cascading errors.

830b0cc98b HLSL: Start location numbering with the entry-point return value.

a05d8b5604 HLSL: Remove recent change to put locations on SV_TARGET*. 
This put locations on members of structures, which is not allowed
in either AST or SPIR-V.

This was caught by asserts in the debug build.

6a70eb7161 HLSL: Emulate write-to-output on return-from-entry-point, for return value. 
This fixes issue #487 and #480.
It also correctly handles output parameters from the entry point.

e3f2c8f98a HLSL: Include shape-changing conversions in overloaded signature selection. 
This also enables vecN -> vec1 shape conversions for all places doing shape
conversions.

For signature selection, makes shape changes worse than any other comparison
when deciding what conversions are better than others.

32c169dbdf Front-end: Warn for likely missed change in default precisions. 
This is part of the change to have desktop shaders respect precision
qualifiers on Vulkan, but since the defaults are all highp, and that's
different from ES fragment shaders, detect likely cases and warn about
them (but being careful to not be too noisy if it's unlikely to be a
problem).

54571c2519 Vulkan: Have desktop shaders respect precision qualifiers. 
Sets highp defaults for the appropriate types, for all stages,

fixing some qualifier orders for desktop built-in declarations
for pre-420 shaders.

as well.
