This PR install the signal stack handler to more signals (SIGILL, SIGTRAP, SIGABRT, SIGFPE, SIGBUS, SIGQUIT).

Noticed in #137138 that we didn't print anything for SIGILL, so I though we could just handle more signals.

No, we should not try to handle every signal in this way.

No, we should not try to handle every signal in this way.

For the record, I took the list from LLVM own signal handling, https://github.com/llvm/llvm-project/blob/6812fc02fbb81d679f95d5c3e15768ae11e1bad8/llvm/lib/Support/Unix/Signals.inc#L218-L224.

Removed the ones you didn't wanted.

I do not care what LLVM does, no.

Half of the entire point of why I worked on this handler is to make it easier to diagnose when the problem is in LLVM and then file an issue with them. The entire file constitutes a sort of disagreement with LLVM about how errors should be handled.

I did intend to add a SIGILL handler but originally I intended to make it slightly more clever when doing so, because I wanted to make it sharper and the diagnostics significantly different if it detected when the error was specifically in LLVM's code. Unfortunately then I discovered doing so would require a more extensive rewrite of a number of things, so I didn't get around to it.

Thank you for doing this. Quibbles about what signals we should be intercepting aside, I ought to have done this long ago, so I'm glad that someone who could do it without immediately getting sidetracked by advanced backtrace formatting nonsense did it.
