Add -flimit to glslc to support shader resource limits.
glslc -flimit= ignores language options.
Those aren't really resource limits. But they do appear
in glslangValidator configuration files. Ignore them.
Add -flimit-file to read resource limits from a file.
Add --show-limits to show default values, and valid input format.
Add ParseResourceLimits internal function.

-Dmacro[=defn] Add an implicit macro definition.
-E Outputs only the results of the preprocessing step.
Output defaults to standard output.
+ -fentry-point=<name>
+ Specify the entry point name for HLSL compilation, for
+ all subsequent source files. Default is "main".
+ -flimit=<settings>
+ Specify resource limits. Each limit is specified by a limit
+ name followed by an integer value. Tokens should be
+ separated by whitespace. If the same limit is specified
+ several times, only the last setting takes effect.
+ --show-limits Display available limit names and their default values.
+ -flimit-file <file>
+ Set limits as specified in the given file.
-fshader-stage=<stage>
Treat subsequent input files as having stage <stage>.
Valid stages are vertex, fragment, tesscontrol, tesseval,
geometry, and compute.
- -fentry-point=<name>
- Specify the entry point name for HLSL compilation, for
- all subsequent source files. Default is "main".
-g Generate source-level debug information.
Currently this option has no effect.
--help Display available options.
