  Log Message:
  -----------
  [RISCV] Set mayRaiseFPException = 0 on FCVT_D_W(U). (#133200)

The input is an integer which can't be NAN so the NV(invalid) exception
can't be raised. The conversion is exact so it can't raise NX(inexact),
UF(underflow), or OF(overflow). The instructions are not divide so they
can't raise DZ(divide by zero).

Fixes #133192.
