[conf] Add config variable to disable crash related overrides.
- We do some nasty things w.r.t. installing or overriding signal handlers in order to improve our crash recovery support or interaction with crash reporting software, and those things are not necessarily appropriate when LLVM is being linked into a client application that has its own ideas about how to do things. This gives those clients a way to disable that handling at build time. - Currently, the code this guards is all Apple specific, but other platforms might have the same concerns so I went for a more generic configure name. Someone who is more familiar with library embedding on Windows can handle choosing which of the Windows/Signals.inc behaviors might make sense to go under this flag. - This also fixes the proper autoconf'ing of ENABLE_BACKTRACES. The code expects it to be undefined when disabled, but the autoconf check was just defining it to 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189694 91177308-0d34-0410-b5e6-96231b3b80d8
