Change modifies the countbits intrinsic to use generics in order to
support 64bit countbits on select platforms where this is supported.
On platforms where this is not natively supported, we emulate by
converting the 64-bit type into a uint2 (metal and spir-v).
This should align with the implementation of other uint64_t
intrinsics such as abs, min, max and clamp.
Added new countbits64 test to verify changes.
Updated documentation for 64bit-type-support.html

* WIP: 64 literal diagnostic and truncation.
* Improve how integer truncation is handled/supported.
Added literal-int64.slang test.
Set a suffix on all literals.
Fixed problem on C++ based targets where l suffix was not the same as int() cast. So on C++ derived emitters, int() is used instead of l suffix to have same behavior across targets.
* Add literal diagnostic testing.
* Allow lexer to lex - in front of literals.
* Fix lexing and converting int literal with -.
* Too large small values of floats become inf.
Handling writing inf types out on different targets.
Add function to deterimine if a float literals kind.
* Roll back the support of lexer lexing negative literals.
* Fixed tests broken because of diagnostics numbers.
Improved _isFinite
* Fix compilation on linux.
* Fix problem with abs on linux - use Math::Abs.
* Fix typo.
* * Improve warnings for float literals zeroed
* Improved 64 bit type documentation
* Handle half
* Improved comments
* Fixed tests broken
* Use capital letters for suffixes.
* Make default behavior on outputting a int literal that is an 'int32_t' is cast (not suffix) to avoid platform inconsistencies.
Improve documentation for 64 bit types.
Make tests cover material in docs.
* Fixed tests.
* Rename FloatKind::Normal -> Finite
* Fix half zero check.
