Make `bad_style` a silent alias for `nonstandard_style`

Now only `nonstandard_style` is suggested in `rustc -W help`, but `bad_style` will not produce a warning. Closes #41646.

3587ff58cc Don't complain re missing mut on attempt to partially initialize an uninitialized struct. 
Under the semantics of #54986 (our short term plan), the partial
initialization itself will signal an error. We don't need to add noise
to the output by also complaining about `mut`. (In particular, the
user may well revise their code in a way that does not require `mut`.)

57c467824b Cleanup fn is_mutable by removing some unnecessary control-flow breaks. 
(This makes it a little easier to add instrumentation of the entry and
exit by adding `debug!` at the beginning and end, though note that the
function body *does* use the `?` operator...)

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.
