Rollup merge of #135409 - Shunpoco:issue-133117-ICE-never-false-edge-start-block, r=Nadrieril
Fix ICE-133117: multiple never-pattern arm doesn't have false_edge_start_block

Fixes #133117 , and close fixes #133063 , fixes #130779

In order to fix ICE-133117, at first I needed to tackle to ICE-133063 (this fixed 130779 as well).

### ICE-133063 and ICE-130779
This ICE is caused by those steps:
1. An arm has or-pattern, and all of the sub-candidates are never-pattern
2. In that case, all sub-candidates are removed in remove_never_subcandidates(). So the arm (candidate) has no sub-candidate.
3. In the current implementation, if there is no sub-candidate, the function assigns `pre_binding_block` into the candidate ([here](https://github.com/rust-lang/rust/blob/master/compiler/rustc_mir_build/src/builder/matches/mod.rs#L2002-L2004)). However, otherwise_block should be assigned to the candidate as well, because the otherwise_block is unwrapped in multiple place (like in lower_match_tree()). As a result, it causes the panic.

I simply added the same block as pre_binding_block into otherwise_block, but I'm wondering if there is a better block to assign to otherwise_block (is it ok to assign the same block into pre_binding and otherwise?)

### ICE-133117
This is caused by those steps:
1. There are two arms, both are or-pattern and each has one match-pair (in the test code, both are `(!|!)`), and the second arm has a guard.
2. In match_candidate() for the first arm, it expands the second arm’s sub-candidates as well ([here](https://github.com/rust-lang/rust/blob/master/compiler/rustc_mir_build/src/builder/matches/mod.rs#L1800-L1805)). As a result, the root candidate of the second arm is not evaluated/modified in match_candidate(). So a false_edge_start_block is not assigned to the candidate.
3. merge_trivial_subcandidates() is called against the candidate for the second arm. It just returns immediately because the candidate has a guard. So a flase_edge_start_block is not assigned to the candidate also in this function.
4. remove_never_subcandidates() is called against the candidate. Since all sub-candidates are never-pattern. they are removed.
5. In lower_match_tree(), since there is no sub-candidate for the candidate, the candidate itself is evaluated in visit_leave_rev ([here](https://github.com/rust-lang/rust/blob/master/compiler/rustc_mir_build/src/builder/matches/mod.rs#L1532)). Because the candidate has no false_edge_start_block, it causes the panic.

So I modified the order of if blocks in merge_trivial_subcandidates() to assign a false_edge_start_block if the candidate doesn't have.

README.md add note not to re-report crashes from crashes tests 2024-11-06 18:07:47 +01:00

This is serves as a collection of crashes so that accidental ICE fixes are tracked. This was formally done at https://github.com/rust-lang/glacier but doing it inside the rustc testsuite is more convenient.

It is imperative that a test in the suite causes an internal compiler error/panic or makes rustc crash in some other way. A test will "pass" if rustc exits with something other than 1 or 0.

When adding crashes from https://github.com/rust-lang/rust/issues, the issue number should be noted in the file name (12345.rs should suffice) and also inside the file via //@ known-bug #4321 if possible.

If you happen to fix one of the crashes, please move it to a fitting subdirectory in tests/ui and give it a meaningful name. Also please add a doc comment at the top of the file explaining why this test exists. :) Adding Fixes #NNNNN Fixes #MMMMM to the description of your pull request will ensure the corresponding tickets will be closed automatically upon merge. The ticket ids can be found in the file name or the known-bug annotation inside the testfile.

Please do not re-report any crashes that you find here!
