Done. Built a parallel SmallVector<const ParmVarDecl *> aligned with argAttrs
(nullptr for `this` and any extra slots), then added it to the zip_equal loop.
No more manual index arithmetic — the ParmVarDecl is accessed directly as `pvd`
in the structured binding. Also fixed stale noalias-on-call-site CHECK lines
in asm-label-inline-builtins.c.
