[RISCV] Update some tests to use floating point ABI where it makes sense.
Trying to reduce the diffs from D118333 for cases where it makes
more sense to use an FP ABI.

[RISCV] Use AdjustInstrPostInstrSelection to insert a FRM dependency for scalar FP instructions with dynamic rounding mode.
In order to support constrained FP intrinsics we need to model FRM
dependency. Whether or not a instruction uses FRM is based on a 3
bit field in the instruction. Because of this we can't add
'Uses = [FRM]' to the tablegen descriptions.
This patch examines the immediate after isel and adds an implicit
use of FRM. This idea came from Roger Ferrer Ibanez.
Other ideas:
We could be overly conservative and just pretend all instructions with
frm field read the FRM register. Or we could have pseudoinstructions
for CodeGen with rounding mode.
