[RISCV] Pass f32/f64 directly without a bitcast for Zfinx/Zdinx. (#107464)
With Zfinx/Zdinx, f32/f64 are legal types for a GPR, we don't need a
bitcast.
This avoids turning fneg/fabs into bitwise operations purely because of
these bitcasts. If the bitwise operations are faster for some reason on
a Zfinx CPU, then that seems like it should be done for all fneg/fabs,
not just ones near function arguments/returns.
I don't have much interest in Zfinx, this just makes the code more
similar to what I proposed for Zhinx in #107446.
