Support #pragma weak for PCH. llvm-svn: 110323

// Test this without pch.
Add 'not' to commands that are expected to fail. This is at least good documentation, but also opens the possibility of using pipefail. llvm-svn: 185652

Bring r325915 back. The tests that failed on a windows host have been fixed. Original message: Start setting dso_local for COFF. With this there are still some GVs where we don't set dso_local because setGVProperties is never called. I intend to fix that in followup commits. This is just the bare minimum to teach shouldAssumeDSOLocal what it should do for COFF. llvm-svn: 325940
