8362aa2178 Extract localStorage tests out into a helper method; use in getCurrentValue() 
1. Extract the tests for whether or not we have workable localStorage out into
   a helper method, so it can be more easily reused
2. Use it in getCurrentValue() too, for the same reasons, as suggested in code

df0d6ad9c1 Auto merge of #55023 - euclio:llvm-error-handler, r=cuviper 
Exit with code 101 on fatal codegen errors

Fixes #54992.

This PR installs a custom fatal error handler that prints the error from LLVM and exits with 101. There should be no visible change in the output from LLVM. This allows distinguishing a fatal LLVM error with a compilation error by exit code.

This PR also modifies the LLVM codegen backend to ICE instead of emitting a fatal error when encountering a LLVM worker thread panic for the same reason.

ca52427d06 make TypeRelating take an infcx again 
At some point, I had thought to use this code to handle equality
comparisons for the `IfEq` verify bounds; at that point, we might not
have had an infcx to talk about. But we wound up doing "SCC
representatives" instead, so that's fine.

Rollup merge of #55060 - jannic:patch-1, r=joshtriplett 
clarify pointer add/sub function safety concerns

Ralf Jung made the same changes to the offset functions' documentation
in commit fb089156. As add/sub just call offset, the same limitation
applies here, as well.

I did not copy the whole explanation ("In particular, the resulting pointer may *not* be used to access a different allocated object [...]") because I'd consider that as being too repetitive. The documentation of add/sub already refers to the offset function, so people interested in the details can look it up, there.
But changing 'an object' to 'the same object' is a small change which improves clarity a lot.

Rollup merge of #55025 - ehuss:missing-lifetime-err-msg, r=petrochenkov 
Add missing lifetime fragment specifier to error message.

A very minor issue, `lifetime` was missing from the error list.
I left `literal` in the list, even though it is unstable. It looks like it may stabilize soon anyways.

05f67ca1a2 remove the sub/super terminology for universes 
Instead, we talk about:

- creating the "next" universe
- universes "extending" one another
- and `u1.can_name(u2)`, meaning that `u1` contains all names from `u2`
