Remove multi-dimensional array support from the parser.
Previously, our AST structures would include a "sizeCount" for arrays,
which indicated the number of AST nodes associated with array
dimensions. Since GLSL only supports a single array dimension, this
field has been replaced with "isArray," a boolean indicating whether we
have a single AST node for array size. This allowed many array-size
based looping constructs to be replaced with simpler non-looping
equivalents.
This change flushed out a few places where the parser was not actually
enforcing its promised maximum array-dimensionality.
Also found some duplicated code in variable-declaration parsing,
related to parsing array-sizes and initializer expressions. This has
been de-duplicated by using a lambda. (This change was likely why this
CL was not net-negative for LOC, but it's simpler and cleaner.)
