*	[DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label.	Shiva Chen	2018-05-09	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	In order to set breakpoints on labels and list source code around labels, we need collect debug information for labels, i.e., label name, the function label belong, line number in the file, and the address label located. In order to keep these information in LLVM IR and to allow backend to generate debug information correctly. We create a new kind of metadata for labels, DILabel. The format of DILabel is !DILabel(scope: !1, name: "foo", file: !2, line: 3) We hope to keep debug information as much as possible even the code is optimized. So, we create a new kind of intrinsic for label metadata to avoid the metadata is eliminated with basic block. The intrinsic will keep existing if we keep it from optimized out. The format of the intrinsic is llvm.dbg.label(metadata !1) It has only one argument, that is the DILabel metadata. The intrinsic will follow the label immediately. Backend could get the label metadata through the intrinsic's parameter. We also create DIBuilder API for labels to be used by Frontend. Frontend could use createLabel() to allocate DILabel objects, and use insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.

*	Verifier: Ignore CUs pulled in by ODR-uniqued types.	Adrian Prantl	2017-10-18	1	-0/+102
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	When more than one Module is imported into the same context, such as during an LTO build before linking the modules, ODR type uniquing may cause types to point to a different CU. This check does not make sense in this case. This fixes the error reported in PR34944. https://bugs.llvm.org/show_bug.cgi?id=34944 rdar://problem/34940685 This reapplies a cleaner implementation of r316049. llvm-svn: 316052
