This commit combines the initial commit (7c240de609af), a fix for x86_64 Linux (3a0581501e76) and a fix for thinko in a last minute rewrite that I really should have run the testsuite on. Also, make sure that all the "I need to step over watchpoint" plans execute before we call a public stop. Otherwise, e.g. if you have N watchpoints and a Signal, the signal stop info will get us to stop with the watchpoints in a half-done state. Differential Revision: https://reviews.llvm.org/D130674
