cb261e3c21 License headers: s/Google/The Khronos Group 
This was a copy-paste screwup, where the first line of the copyright had the company name was updated, but the company name mid way though was not.

b8c3386ec0 CMake: break up glslang into smaller static libs 
Add `GenericCodeGen` and `MachineIndependent` static library targets.
Privately import both of these into the `glslang` target.
Privately import `MachineIndependent` into the  `SPIRV` target.

This is done to break the dependency of `libglslang.so` non-public APIs from `libspirv.so`,
which will become problematic once `glslang` hides its non-public symbols.

12c155f303 SPV: RelaxedPrecision: use the result precision for texture sampling. 
Fix #2298.

The AST has two precisions, an operation precision and a result precision.
Actual use of GLSL with mediump samplers wants the result precision, so
pick that up instead of the operation precision.

435dd8028b SPV: RelaxedPrecision: Generalize fix #2293 to cover more operations. 
This simplifies and enforces use of precision in many more places,
to help avoid accidental loss of RelaxedPrecision through intermediate
operations. Known fixes are:
- ?:
- function return values with mis-matched precision
- precision of function return values when a copy was needed to fix types

bf6efd0316 SPV: Fix #2293: keep relaxed precision on arg passed to relaxed param 
When arguments are copied to make space for a writable formal parameter,
and the formal parameter is relaxed precision, make the copy also
relaxed precision.

4df10335e6 SPV: Partially address #2293: correct "const in" precision matching. 
Track whether formal parameters declare reduced precision and match
that with arguments, and if they differ, make a copy to promote the
precision.

060882fd37 Update SPIR-V generator version 
Change to 10 to reflect the change to generating unordered !=
operations.

65ce566cbc Use OpFUnordNotEqual for floating-point != 
The normal IEEE not equal operation tests whether operands are unordered
or not equal (so comparison with a NaN returns true). This corresponds
to the SPIR-V OpFUnordNotEqual, so change to using that.

d52dce5067 Add -g0 command line argument 
Analogous to gcc, -g0 would strip all debug info.  This is done
regardless of whether optimizations are enabled.

f15982ebeb Remove install to the SPIRV/ folder. (#2256) 
This CL updates the build scripts to only install to glslang/SPIRV
instead of also installing to the SPIRV/ folder. The deprecation notice
is also removed.

Note, this may cause downstream build issues if include directories have
not been updated

4d2298bfd7 Support multiple swizzled out operands (#2175) 
Swizzled out operands were added in bbbd9a2a. This was sufficient
for most tests, but we ran into problems with umulExtended and
imulExtended, which have two.

This CL converts the tracking values to vectors so multiple operands
can be supported.

fb18b6df28 Fix an issue of SPV generation for imageAtomicStore. 
For GLSL function imageAtomicStore, it will be translated to
OpImageTexelPointer + OpAtomicStore. The result type of
OpImageTexelPointer must be the same as the sampled type of OpTypeImage.
On translation, the result type is mistakenly fetched from operand list
operands[2] while operands[2] corresponds to sampleNum whose type is
always uint. This leads to an error if the image type is iimageXXX that is
int image.
