[modules] Turn off a broken optimization: we need to pick up implicit special members from all redefinitions of a class that have them, in case the special member is defined in one module but only declared in another. llvm-svn: 215675

Wrap clang module files in a Mach-O, ELF, or COFF container. This is a necessary prerequisite for debugging with modules. The .pcm files become containers that hold the serialized AST which allows us to store debug information in the module file that can be shared by all object files that were built importing the module. This reapplies r230044 with a fixed configure+make build and updated dependencies and testcase requirements. Over the last iteration this version adds - missing target requirements for testcases that specify an x86 triple, - a missing clangCodeGen.a dependency to libClang.a in the make build. rdar://problem/19104245 llvm-svn: 230423

Emit DeferredDeclsToEmit in a DFS order. Currently we emit DeferredDeclsToEmit in reverse order. This patch changes that. The advantages of the change are that * The output order is a bit closer to the source order. The change to test/CodeGenCXX/pod-member-memcpys.cpp is a good example. * If we decide to deffer more, it will not cause as large changes in the estcases as it would without this patch. llvm-svn: 226751
