LibCpp: Support for parsing c-style fixed arrays (arr[2])

Also adds tests for finding declaration of arrays inside
CppComprehension which requires proper parsing for passing.

Side-effect of this patch: if we ctrl+click on array variables, it
should jump to the correct declaration inside HackStudio.
