Possibly related to https://bugs.llvm.org/show_bug.cgi?id=41035.
declaring bcmp as an alias to memcmp, then using memcmp in a way that it would
be lowered to a bcmp is resulting in the compiler not exiting.
Attached is a test case. Observable at -O1 and above, but not -O0.
Instead, I can work around this with an explicit tail call, but it's curious as
to why the addition of the alias causing the compiler to hang.
