Literal handling improvements (#1202)
* 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.
