Rewrite llvm.flt.rounds to "1" for now, and disallow llvm.flt.rounds.
Until there is an intrinsic to *set* the rounding mode,
this intrinsic to *get* the rounding mode isn't so useful.
Separately we will add a test that for each platform, the
initial rounding mode is "1" (round to nearest). That is
the case right now for x86, ARM, and MIPS.
