[PDB] Write public symbol records and the publics hash table Summary: MSVC link.exe records all external symbol names in the publics stream. It provides similar functionality to an ELF .symtab.

Make a DLL that exports a few functions, then make a DLL with PDBs that imports
them. Check that the __imp_ pointer and the generated thunks appear in the
publics stream.

[PDB] Fix section contributions Summary: PDB section contributions are supposed to use output section indices and offsets, not input section indices and offsets. This allows the debugger to look up the index of the module that it should look up in the modules stream for symbol information. With this change, windbg can now find line tables, but it still cannot print local variables.

[PDB] Fix an issue writing the publics stream. In the refactor to merge the publics and globals stream, a bug was introduced that wrote the wrong value for one of the fields of the PublicsStreamHeader. This caused debugging in WinDbg to break. We had no way of dumping any of these fields, so in addition to fixing the bug I've added dumping support for them along with a test that verifies the correct value is written. llvm-svn: 310439
