CUDA half comparison support (#1834)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Split out StringEscapeUtil.

* Added StringEscapeUtil.

* Fix typo in unix quoting type.

* Small comment improvements.

* Try to fix linux linking issue.

* Fix typo.

* Attempt to fix linux link issue.

* Update VS proj even though nothing really changed.

* Fix another typo issue.

* Fix for windows issue.
Fixed bug.

* Make separate Utils for escaping.

* Fix typo.

* Split out into StringEscapeHandler.

* Windows shell does handle removing quotes (so remove code to remove them).

* Handle unescaping if not initiating using the shell.

* Slight improvement around shell like decoding.

* Simplify command extraction.

* Add shared-library category type.

* Fix bug in command extraction.

* Typo in transcendental category.

* Enable unit-test on in smoke test category.

* Make parsing failing output as a failing test.

* Fixes for transcendental tests. Disable tests that do not work.

* Changed category parsing.

* Removed the TestResult parameter from _gatherTestsForFile.
Made testsList only output.

* Remove testing if all tests were disabled.

* Make args of CommandLine always unescaped.

* Add category.

* Don't need escaping on unix/linux.

* Remove some no longer used functions.

* Add requireSMVersion to CUDAExtensionTracker.

* half-calc.slang now works for CUDA.

* bit-cast-16-bit works on CUDA.

* WIP handling of CUDA vector<half> types.

* Half swizzle CUDA.

* Half vector test.

* Fix swizzle half bug.

* Fix compilation issue with narrowing to Index.

* Add unary ops.

* Add some vector scalar maths ops.

* Add half vector conversions for CUDA.

* Fix erroneous comment.

* Support for half comparisons.

* First pass test for half compare.

* Fix bug in CUDA specialized emit control.
Updated tests to have pre and post inc/dec.

* Removed unneeded parts of the cuda prelude.

* Half structured buffer works on CUDA.
