test-timeout.cpp
The time it takes to require one of our internal tests recently jumped from
about 1 second to roughly 30 seconds after upstream change
9d070b2f4889887f9ce497592ef01df7b9601a1c.
To reproduce the issue, build the attached file test-timeout.cpp with "-S -g"
on a Windows hosted compiler targeting the PS4 (--target=x86_64-scei-ps4).
Those two options seem critical to reproduce the compilation slowdown.
Comparing the time reports before and after they look similar, the main
difference that the PrintModulePass goes from taking a fraction of a second
(0.1679 wall time to 33.9767)</pre>
