[committed][RISC-V] Fix nearbyint failure on rv32 and formatting nits
The CI system tripped an execution failure for rv32 with the ceil/round patch.
The fundamental problem is the FP->INT step in these sequences requires the
input size to match the output size. The output size was based on rv32/rv64.
Meaning that we'd try to do DF->SI->DF.
That doesn't preserve the semantics we want in at least two ways.
The net is we can't use this trick for DF values on rv32. While inside the
code I realized we had a similar problem for HF modes. HF modes we can support
only for Zfa. So I fixed that proactively.
The CI system also pointed out various formatting nits. I think this fixes all
but one overly long line.
Note I could have factored the TARGET_ZFA test. But I think as-written it's
clearer what the desired cases to transform are.
