Emit noalias on &mut parameters by default
This used to be disabled due to LLVM bugs in the handling of noalias information in conjunction with unwinding. However, according to #31681 all known LLVM bugs have been fixed by LLVM 6.0, so it's probably time to reenable this optimization. Noalias annotations will not be emitted by default if either -C panic=abort (as previously) or LLVM >= 6.0 (new). -Z mutable-noalias=no is left as an escape-hatch to allow debugging problems suspected to stem from this change.
