Bug ID: 39533

Product: clang
Version: 7.0

gdb backtrace
clang version 5.0.1 and 7.0.0 are no longer able to compile our code with -O or
-O2. It works with -O0 or in ASAN mode.
It worked fine with clang 3.9 and earlier with -O2.
The problem is that I don't own the code, and I don't know how to reduce it to
a test case, could you help me ?
It seems to be stuck in CGPassManager::RunPassOnSCC but afterwards the
backtrace is always different.
