CodeGen: Cast llvm.flt.rounds result to match __builtin_flt_rounds llvm.flt.rounds returns an i32, but the builtin expects an integer. On targets where integers are not 32-bits clang tries to bitcast the result, causing an assertion failure. The patch enables newlib build for msp430. Patch by Edward Jones!

[Intrinsic] Rename flt.rounds intrinsic to get.rounding Address the inconsistency between FLT_ROUNDS_ and SET_ROUNDING SDAG node. Rename FLT_ROUNDS_ to GET_ROUNDING and add llvm.get.rounding intrinsic to replace flt.rounds.
