The summary is that clang codegen time has significantly increased on some of our code after this patch, pushing the compile times far beyond the time limit. Here's a reduced test case: F24611479: q.cc <https://reviews.llvm.org/F24611479>

I was expecting this to be a runaway case in isDereferenceableAndAlignedPointer, but this function just has over 27000 loads in it and they all take a similar amount of time
