Rollup merge of #146831 - taiki-e:powerpc-clobber, r=Amanieu
Support ctr and lr as clobber-only registers in PowerPC inline assembly Follow-up to rust-lang/rust#131341. CTR and LR are marked as volatile in all ABIs, but I skipped them in rust-lang/rust#131341 due to they are currently marked as reserved. https://github.com/rust-lang/rust/blob/dd7fda570040e8a736f7d8bc28ddd1b444aabc82/compiler/rustc_target/src/asm/powerpc.rs#L209-L212 However, they are actually only unusable as input/output of inline assembly, and should be fine to support as clobber-only registers as discussed in [#t-compiler > ppc/ppc64 inline asm support](https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/ppc.2Fppc64.20inline.20asm.20support/with/540413845). r? ````@Amanieu```` or ````@workingjubilee```` cc ````@programmerjake```` ````@rustbot```` label +O-PowerPC +A-inline-assembly
