  Log Message:
  -----------
  [RISCV] Add signext attribute to return of fmv_x_w test in float-convert.ll. NFC

This shows that Zfinx generates a sext.w instruction on RV64.
The fadd.s should have filled the upper bits of the GPR with sign
bits so this is unnecessary. Proving it is unnecessary might be
difficult though.
