    nir/algebraic: Don't put quotes around floating point literals

    The quotation marks around 1.0 cause it to be treated as a string
    instead of a floating point value.  The generator then treats it as an
    arbitrary variable replacement, so any iand involving a ('ineg', ('b2i',
    a)) matches.

    v2: Remove misleading comment about sized literals (suggested by
    Timothy).  Add assertion that the name of a varible is entierly
    alphabetic (suggested by Jason).
