Make const-qualification look at more `const fn`s
As explained in a lot more detail in #67053 this makes const-qualification not ignore the unstable const fns in libcore.
r? @oli-obk cc @ecstatic-morse
(Still a bit unsure about the `cfg`s here, for bootstrapping, does that seem correct ?)
Fixes#67053.
Include a span in more `expected...found` notes
In most places, we use a span when emitting `expected...found` errors.
However, there were a couple of places where we didn't use any span,
resulting in hard-to-interpret error messages.
This commit attaches the relevant span to these notes, and additionally
switches over to using `note_expected_found` instead of manually
formatting the message
weak-into-raw: Clarify some details in Safety
Clarify it is OK to pass a pointer that never owned a weak count (one
from Weak::new) back into it as it was created from it. Relates to
discussion in #60728.
@CAD97 Do you want to have a look at the new docs?
Less minification
The goal of this PR is to remove the minification process on the `search-index.js` file. It provides great result in term of space reduction but the computation time is far too long. I'll work on this issue and will put it back once it's fast enough.

Reorganize borrow check diagnostic code
Currently borrow checker diagnostics are split across many different modules in different places in the `librustc_mir` crate. This moves them all to a `diagnostics` module. This also reduces the nesting of the modules a bit (sooo much nesting).
I am also thinking of moving stuff out of the `nll` module since we only have one borrow checker now (🎉), and maybe it even makes sense to split out all of this stuff to a `librustc_borrow_check`, but those are for the future. Feel free to ping me here or on zulip and let me know what you think...

Use Module::print() instead of a PrintModulePass
llvm::Module has a print() method. It is unnecessary to create a pass just for the purpose of printing LLVM IR.
Only memoize const fn calls during const eval
Miri and other engines may want to execute the function in order to detect UB inside of them.
