Issue Description:
There seems to be a mis-compilation on Linux x86_64 with CFAttributedString
that the rebranch uncovered. @etcwilde and I managed to reduce it down to a single file, but have not reduced it further. Unfortunately, it involves LICM, LoadStoreHoisting, and inlining potentially. In order to unblock the rebranch, this file might need to be optimized at -O0
on linux.
The following are the known failing tests associated with this issue:

Unfortunately, it is very difficult to debug. lldb consistently crashes when trying to execute any of these tests and gdb is unable to show a valid stack trace. Additionally, these only happen on optimized builds, so that throws more fun into the mix.
