Yuanfang Chen afa87767f4 [Diagnose] Unify MCContext and LLVMContext diagnosing ... The situation with inline asm/MC error reporting is kind of messy at the moment. The errors from MC layout are not reliably propagated and users have to specify an inlineasm handler separately to get inlineasm diagnose. The latter issue is not a correctness issue but could be improved. * Kill LLVMContext inlineasm diagnose handler and migrate it to use DiagnoseInfo/DiagnoseHandler. * Introduce `DiagnoseInfoSrcMgr` to diagnose SourceMgr backed errors. This covers use cases like inlineasm, MC, and any clients using SourceMgr. * Move AsmPrinter::SrcMgrDiagInfo and its instance to MCContext. The next step is to combine MCContext::SrcMgr and MCContext::InlineSrcMgr because in all use cases, only one of them is used. * If LLVMContext is available, let MCContext uses LLVMContext's diagnose handler; if LLVMContext is not available, MCContext uses its own default diagnose handler which just prints SMDiagnostic. * Change a few clients(Clang, llc, lldb) to use the new way of reporting.
