deec1933e9 Web: Turn off includes, independent preprocessing path, fine tune all. 
Saved about 21K, size down to 380K of MSVC x86 code.
Fixed one bug that needs to be looked at on the master branch:
The test for needing a Vulkan binding has a bug in it, "!layoutAttachment"
which does not mean "no layoutAttachment", because that is non-zero.
This is why some test and test results changed.

fb4f2333da Web: Use isEsProfile() instead of run-time testing; remove more atomics

39697cdb9d Web: Remove unnecessary GLSL numeric types, and some collateral. 
This saves another 40K of x86 binary, which is about 13% of the target size.

7015bd658e Web: Remove/rationalize a set of *_EXTENSIONS, using GLSLANG_WEB. 
Focus was on the front end (not SPIR-V), minus the grammar.
Reduces #ifdef count by around 320 and makes the web build 270K smaller,
which is about 90% the  target size.

The grammar and scanner will be another step, as will the SPIR-V backend.
This makes heavy use of methods #ifdef'd to return false as a global way
of turning off code, relying on C++ DCE to do the rest.

6225dd4ba1 PP: Faithfully track white-space through macro record/use, fixing bugs: 
This fixes the comparison in macro body redefinitions, where initial
white-space differences do not matter, but internal white-space differences
do matter.

5cdf3c5a23 PP: Non-functional: Remove the sub-tokenization of macro stream record. 
This has been a continually fragile area. Switching to a vector of real
objects, instead of a linearized stream of characters, removes a bunch of
code and generally makes this area more robust.

3e8e9f7bbd PP: Implement locale-independent strtod, using istringstream and a fast path. 
Fixes #1228. Fixes #234.

This uses imbue() to be locale independent.  Notes:

- 'sstream >> double' is much slower than strtod()
  * this was measurable in the test suite as a whole, despite being
    a tiny fraction of what the test suite does
- so, this embeds a fast path that bypasses sstream most of the time
  => the test suite is faster than before
- sstream is probably slower, because it does more accurate rounding than strtod()
- sstream does not create INFINITY by itself, this was done based on failure inferencing

6c52f8968c PP: Remove second parsing of numbers recorded in macros; save/use original. 
This partly addresses #1228 and #234 by reducing usage of strtod (or atof).
There is now only place to parse a floating-point number.

e7e081bda9 PP: don't give errors on some tokens under #if 0 (or similar). 
Fixes #1295.

Tokens that are accepted by any version of HLSL or GLSL should be
allowed when #ifdef'd off, such that errors are not reported.

9c6f8cc29b Scanner: Many int16 and float16 fixes, including performance. 
- fixes #1209, addresses most of #1187
- only query feature availability on seeing the feature

- correct case-sensitive checks for multi-character suffixes

c043aadd25 Scanner: Many int64 fixes, including performance. 
- partially addresses #1209 and #1187
- only query 64-bit extension on seeing use of a 64-bit literal
  (was doing it for every single token)
- correct HLSL acceptance of 64-bit literal syntax (still an int though)
- error on overflow of 32-bit literal type

dc756a61c8 Preprocessor: Evaluate INT_MIN / -1 to 0. 
This division is undefined behaviour which raises SIGFPE on x86.
