Re-land "[codeview] Emit information about global variables" This reverts commit r271962 and reinstantes r271957. MSVC's linker doesn't appear to like it if you have an empty symbol substream, so only open a symbol substream if we're going to emit something about globals into it. Makes check-asan pass. llvm-svn: 271965

[codeview] YAMLize all section offsets and indices in symbol records We forgot to serialize these because llvm-readobj didn't dump them. They are typically all zeros in an object file. The linker fills them in with relocations before adding them to the PDB. Now we can properly round trip these symbols through pdb2yaml -> yaml2pdb. I made these fields optional with a zero default so that we can elide them from our test cases. llvm-svn: 305857

[CodeView] Teach clang to emit the .debug$H COFF section. Currently this is an LLVM extension to the COFF spec which is experimental and intended to speed up linking. For now it is behind a hidden cl::opt flag, but in the future we can move it to a "real" cc1 flag and have the driver pass it through whenever it is appropriate. The patch to actually make use of this section in lld will come in a followup. Differential Revision: https://reviews.llvm.org/D40917 llvm-svn: 320649

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769.
