I'd like to compile my C-extensions with ASAN for testing in Windows, but they cannot be loaded as the host python.exe process needs to be compiled with ASAN. 

https://docs.microsoft.com/en-us/cpp/sanitizers/asan?view=msvc-170#ide-msbuild

The EnableASAN flag would be a setting in vcxproj files within the PCBuild solution, and a flag in the build.bat to enable it.

After some experimentation, this can be done if you enable ASAN in all projects except python3dll.vcxproj

I think it would make sense (if this were supported) to have a flag in build.bat like there is for pgo

`build.bat --asan`
