This change seems to have broken `-ffixed-xX`, we've noticed that our kernel started crashing with tip-of-tree Clang. After debugging, we found out that compiler would generate stores to x15 even though we compile with `-ffixed-x15` which breaks the kernel because x15 is used to store per-cpu state. Would it be possible to revert or fix this issue ASAP please?
