(In reply to Nils Beyer from comment #58)
Actually, I'm not so sure now.  If I disassemble
llvm::FoldingSetBase::GrowBucketCount(), I see this computed call:

   0x0000000002c33cea <+250>:   callq  *0x18(%rax)
=> 0x0000000002c33ced <+253>:   mov    0x8(%r12),%rcx

so we could be getting to clang::FunctionProtoType::Profile() by way of some
c++ magic.
