When hitting an lldbassert in a non-assert build, we emit a blurb including the assertion, the triggering file and line and a pretty backtrace leading up to the issue. Currently, this is all printed to stderr. That's fine on the command line, but when used as library, for example from Xcode, this information doesn't make it to the user. This patch uses the diagnostic infrastructure to report LLDB asserts as diagnostic events. The patch is slightly more complicated than I would've liked because of layering. lldbassert is part of Utility while the debugger diagnostics are implemented in Core.
