Add hotness data to LLVM remarks

[Kobzol]

Slight improvement of #113040. This makes sure that if PGO is used, remarks generated using -Zremark-dir will include the Hotness attribute.

r? @tmiasko

[tmiasko]

To avoid compile time impact #114568 (comment), can you also check that PGO information is available before requesting hotness data?

[Kobzol]

Would it be enough to just check if we're currently compiling with -Cprofile-use?

[tmiasko]

Checking for -Cprofile-use sounds good.

[Kobzol]

Ok, done.

That doesn't seem good. I don't really have x86_64-mingw prepared locally, and hints on how to debug the segfault?

[Kobzol]

Oh, ok, that's one way to solve it 😆 Thank you both.
