Nikita Popov b8b7fce446 [PPC][MC] Restore support for case-insensitive register names (#128525)
Lowercase the name before calling MatchRegisterName(), to restore
support for using `%R3` instead of `%r3` and similar, matching the GNU
assembler.

Fixes https://github.com/llvm/llvm-project/issues/126786.

(cherry picked from commit f1252f539ca203a979d61b616186e9be9d612f96)
