mopgobopotandClaude Opus 5.5 d37221a00a fix(relinker): move in-place AMD-only replacements into a short instruction's stub ...

A short AMD-only instruction lowered through a stub takes the following instructions with it. When one of them is an AMD-only instruction that is replaced in place (MOVNTSS, MOVNTSD, MONITORX, MWAITX, and RDSEED and CLWB for Rosetta), MatchSequence found no out-of-line lowering for it and the conversion failed with 'AMD-only instruction sequence has no out-of-line lowering', for example on extrq xmm0,xmm1 followed by movntss [rdi],xmm0. A following instruction with an in-place replacement now has that replacement moved into the stub, with its RIP-relative displacement relocated. Out-of-line emission for 256-bit store windows is unchanged.
