Enable some of profiler tests on Windows-gnu CC rust-lang#61266 Because of force-push GitHub didn't let me reopen rust-lang#75184 Because of the GCC miscompilation, generated binaries either segfault or `.profraw` is malformed. Clang works fine but we can't use it on the CI. However we can still test the IR for the proper instrumentation so let's do it.

@bors r- rollup=iffy Rollup #76350 failed by something that seems suspiciously like it has to be this: On the mingw-windows builder only: https://github.com/rust-lang-ci/rust/runs/1074472443 |

I don't think it's worth investigation whole fault this is: ancient GCC or ancient Binutils. |

Don't build a broken/untested profiler runtime on mingw targets Context: https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Why.20build.20a.20broken.2Funtested.20profiler.20runtime.20on.20mingw.3F rust-lang#75872 added `--enable-profiler` to the `x86_64-mingw` job (to cause some additional tests to run), but had to also add `//@ ignore-windows-gnu` to all of the tests that rely on the profiler runtime actually *working*, because it's broken on that target. We can achieve a similar outcome by going through all the `//@ needs-profiler-support` tests that don't actually need to produce/run a binary, and making them use `-Zno-profiler-runtime` instead, so that they can run even in configurations that don't have the profiler runtime available. Then we can remove `--enable-profiler` from `x86_64-mingw`, and still get the same amount of testing. This PR also removes `--enable-profiler` from the mingw dist builds, since it is broken/untested on that target. Those builds have had that flag for a very long time.
