    Preserve information about dots in numbers across parser rewriting. · 1e4681c3
    bradnelson authored
    Fix several operations in the parser that rewrite constant expressions
    to preserve knowledge regarding whether a value originally contained a ".".
    This information is required to accurately validate Asm.js typing.
    
    Making the assumption that if either side of a binary operation contains
    a dot, that the rewritten expression should be treated as a double for
    Asm.js purposes. This is a slight deviation from the spec (which
    would forbid mix type operations).
