Subject: [PATCH 1/3] Fix encoding/decoding of string literals for big-endian
systems
Per SPIR-V spec, a string literal's UTF-8 octets are encoded packed into
words with little-endian convention. Explicitly perform that encoding
instead of assuming that the host system is little-endian.
Note that this change requires corresponding fixes in SPIRV-Tools.
Fixes #202

Subject: [PATCH 2/3] TIntermediate::promoteConstantUnion(): fix conversion to
int8
The signedness of type char is implementation-defined in C++. The
conversion to (signed) int8 currently uses a cast to char, which is
undefined for negative values when the type char is implemented as
unsigned. Thus, fix to cast to "signed char", which has the intended
semantic on all implementations.
Fixes #2807

Subject: [PATCH 3/3] Use intermOut.cpp's IsNan and IsInfinity for parse-time
constant folding (updated)
There were two implementations of isInf() and isNan(), in Constant.cpp
and in intermOut.cpp. The former only works on little-endian systems,
the latter is a wrapper for library functions and works regardless of
endianness. Move the second version into Common.h and adopt it in both
places. Thereby avoid the duplication and fix for big-endian systems.
A previous commit with the same intent and purpose had missed a required
header for builds on Windows.
On s390x, this fixes the test case
Glsl/CompileToAstTest.FromFile/constFold_frag.
Fixes #2802
