[PATCH] D39469: [asan] Add CMake hook to override default shadow scale

[Kostya Serebryany via Phabricator via llvm-commits]

kcc added a comment.

--asan-maping-scale is an -mmlv flag. 
Such flags should not be given to users -- they are internal testing only flags.

All this #ifdef stuff really sucks. I don't claim I immediately see a better way to do this, but pleeeeeease, try to avoid such ifdefs when possible.
