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.

  postfix

9c6f8cc29b Scanner: Many int16 and float16 fixes, including performance. 
- fixes #1209, addresses most of #1187
- only query feature availability on seeing the feature
  (was doing it for every single token)
- 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.
  Most C++ preprocessors evaluate this silently to 0.

8e204b2d67 [lumped builds] Only define _CRT_SECURE_NO_WARNINGS if it’s not defined yet. 
When glslang is built with some other build system and lumped/unity builds are used,
without the checks this would get “macro is being redefined” warnings/errors.

197082ca34 Fix build warnings on some platforms 
Use an explicit cast from size_t to int to avoid errors like the following:
glslang\glslang\MachineIndependent\preprocessor\Pp.cpp(1053) : error C2220: warning treated as error - no 'object' file generated
glslang\glslang\MachineIndependent\preprocessor\Pp.cpp(1053) : warning C4267: '=' : conversion from 'size_t' to 'int', possible loss of data

affects Pp.cpp, hlslParseHelper.cpp.

Initialize local variable to get rid of warningsa about potentially
uninitialized variables:
glslang\hlsl\hlslparsehelper.cpp(3667) : error C2220: warning treated as error - no 'object' file generated
glslang\hlsl\hlslparsehelper.cpp(3667) : warning C4701: potentially uninitialized local variable 'builtIn' used

affects hlslParseHelper.cpp
