[REQUEST]: MingW Clang ASAN features

[partouf]

Is your feature request related to a problem? Please describe

We're missing address sanitizer functionality on our MingW Clang compilers. This may or may not be fixable.

If it's fixible, we may or may not have to apply some copying mechanism here https://github.com/compiler-explorer/compiler-explorer/blob/main/lib/win-utils.ts#L34 - as they might be dynamically linked libraries that objdump won't catch.

Describe the solution you'd like

I have posted an issue in the repo where we get our binary distributions brechtsanders/winlibs_mingw#200

Describe alternatives you've considered

Build our own distribution - but that would be insanity

Additional context

Not applicable

The recommendation was to use builds from https://github.com/mstorsjo/llvm-mingw instead for Clang/LLVM
