syntax: don't treat `as` and `from` as reserved keywords

ECMAScript allows using `as` and `from` as identifiers so follow suit
and don't treat them specially while parsing. Extend the compiler logic
instead to check for TK_LABEL tokens with the expected value to properly
parse import and export statements.
