[clang] [clang][RISCVVEmitter] Remove no-op ptr-to-ptr bitcast (NFC) (PR #74179)

[Youngsuk Kim via cfe-commits]

https://github.com/JOE1994 created https://github.com/llvm/llvm-project/pull/74179

Remove ptr-to-ptr bitcast which was added back in 939352b6ec31db4e8defe07856868438fbc5340d . With opaque pointers, the bitcast is now redundant.

Opaque ptr cleanup effort.
