Fix substitution parts having a shifted underline in some cases

If two suggestions parts are side by side, the underline's offset:

```
The emitter didn't take into account that the string had shrunk/grown if two substitution parts were side-by-side (surprisingly, there was only one case in the ui testsuite.)

miri core/alloc tests: do not test a 2nd target

check-aux seems to be one of the slowest runners since we started running standard library tests in Miri on it. So maybe it'd be better to reduce test coverage a bit by not doing cross-target testing of core and alloc? I don't recall finding target-specific issues in these libraries ever (and we still have the extra test coverage via our [out-of-tree nightly tests](https://github.com/rust-lang/miri-test-libstd)). This gives us more buffer to deal with the fact that the number of tests we run will only grow over time.

Do not ICE on invalid consts when walking mono-reachable blocks

The `bug!` here was written under the logic of "this condition is impossible, right?" except that of course, if the compiler is given code that results in an compile error, then the situation is possible.

So now we just direct errors into the already-existing path for when we can't do a mono-time optimization.

add more tests

doc: Make the `mod.rs` in the comment point to the correct location

The origin `mod.rs` had moved to `rustc_hir_analysis::check`, but the annotation doesn't point to it.

See [the origin PR](https://github.com/rust-lang/rust/pull/61857/files#diff-b65997b61ccd8d8e08238c925d631207671aca506e93ce7c5cfa0bec134c0a8e).
