[Mesa-dev] MR: nir/algebraic: Don't put quotes around floating point literals

NOTE: This is still running through our CI, and I'm trying to come up
with a piglit test case that will reproduce it.

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.
