This is an alternative to part of #101608. Using FP as the base type allows the
existing Zfh extension check to work.
This does not fix fp->int narrowing instructions which still use the narrow
integer type as their base type.

Subject: [PATCH] [RISCV] Use FP type as the base type for some int->f
conversions.
This is an alternative to part of #101608. Using FP as the base
type allows the existing Zfh extension check to work.
This does not fix fp->int narrowing instructions which still use
the narrow integer type as their base type.
