[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.

Reland r330223, "COFF: Merge .idata, .didat and .edata into .rdata by default.", which was reverted in r330228. In this reland I removed an unnecessary use of /debug in the test delayimports32.test and used the /pdbaltpath flag in the test pdb-publics-import.test, both of which avoid embedding absolute PDB paths in executables which could affect later RVAs.

[LLD][COFF] Generate import modules & COFF groups in PDB Generate import modules for each imported DLL, along with its symbol stream. Also create COFF groups in the * Linker * module, one for each PartialSection (input, unmerged sections) Currently COFF groups are disabled for MINGW because it significantly increases PDB sizes. We could enable that later with an option. The overall objective for this change is to support code hot patching tools. Such tools need to know the import libraries used, from the PDB alone.

[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
