Windows/Clang build instrumented/PGO
Hello LLVM developers,
Following some hints on this mailing list earlier this year on how to make
clang faster than stock llvm.org builds I have implemented a script that
builds a PGO optimized version of clang by following the guide here:
http://llvm.org/docs/HowToBuildWithPGO.html
This works great on macOS and Linux - we gained almost 15% in our project
with this technique. I am now looking at

Asan self host problems: Failed to deallocate
I wish there was something like the line in config.log that would show the
CMake command, but instead I can at least show you the CMakeCache files for
my release build and asan build (attached to this email).
No lld, so far as I know - believe I'm using gold at the moment for both
builds.
Did just reproduce this with a clean release build and a clean asanified
