And expose it in Signals.h, allowing clients to call it directly, possibly LLVMErrorHandler which currently calls RunInterruptHandlers but not RunSignalHandlers, thus for example not printing the stack backtrace on Unixish OSes. On Windows it does happen because RunInterruptHandlers ends up calling the callbacks as well via Cleanup(). This difference in behaviour and code structures in */Signals.inc should be patched in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242936 91177308-0d34-0410-b5e6-96231b3b80d8
