  [RISCV] Remove -mattr=+no-rvc-hints (#145138)

As far as I know binutils does not have a similar option and I don't
know of a reason we shouldn't accept the RVC hint instructions.

The wording in the spec in the past suggested that maybe these
weren't valid instruction names, but that's been modified recently.
