[llc] New diagnostic handler Without a diagnostic handler installed, llc's behaviour is to exit on the first error that it encounters. This is very different from the behaviour of clang and other front ends, which try to gather as many errors as possible before exiting. This commit adds a diagnostic handler to llc, allowing it to find and report more than one error. The old behaviour is preserved under a flag (-exit-on-error). Some of the tests fail with the new diagnostic handler, so they have to use the new flag in order to run under the previous behaviour. Some of these are known bugs, others need further investigation. Ideally, we should fix the tests and remove the flag at some point in the future. Reapplied after fixing the LLDB build that was broken due to the new DiagnosticSeverity in LLVMContext.h, and fixed an UB in the new change. Patch by Diana Picus. llvm-svn: 269655

[PowerPC] Don't return unsupported register classes for asm constraints As a follow-up to r251566, do the same for the other optionally-supported register classes (mostly for vector registers). Don't return an unavailable register class (which would cause an assert later), but fail cleanly when provided an unsupported inline asm constraint. llvm-svn: 251575
