Use query to determine whether function needs const checking

[ecstatic-morse]

Resolves #69615.

The HIR const-checker was checking the constness of a function's fn_sig to determine whether a function needed const-checking. Now that const trait impls are a thing, this is no longer enough. All code should use the is_const_fn_raw query instead, which takes the constness of the impl block into account.

[ecstatic-morse]

Not sure what's up with the diagnostics changes. I assume that invoking is_const_fn_raw at this point in compilation changes the order in which other queries are evaluated. It appears that some additional errors are being emitted, however. It's not just a change in their order.

[oli-obk]

Some (I haven't checked all of them) of the additional errors look to me like they would happen if the other errors didn't happen before, so maybe this is just a case of some queries being triggered that would have otherwise not gotten triggered at all because of errors happening before them?

[oli-obk]

You can check this by looking at the query stack with -Ztreat-err-as-bug=42 where 42 is the index of the new error (=0 is the first error)

[bors]

☔ The latest upstream changes (presumably #68944) made this pull request unmergeable. Please resolve the merge conflicts.

[Dylan-DPC-zz]

@ecstatic-morse any updates? also you have a conflict to resolve :)

[ecstatic-morse]

@oli-obk I preserved the existing query order by calling tcx.hir().get_foreign_abi() instead of tcx.fn_sig().abi() (see the last commit). This should be ready to go.
