Guillaume Gomez 470c4f94e8 Rollup merge of #133452 - taiki-e:hexagon-asm-pred, r=Amanieu ... Support predicate registers (clobber-only) in Hexagon inline assembly The result of the Hexagon instructions such as comparison, store conditional, etc. is stored in predicate registers (`p[0-3]`), but currently there is no way to mark it as clobbered in `asm!`. This is also needed for `clobber_abi` (although implementing `clobber_abi` will require the addition of support for [several more register classes](https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/Hexagon/HexagonRegisterInfo.cpp#L71-L90). see also https://github.com/rust-lang/rust/issues/93335#issuecomment-2395210055).
