Tim Northover c5978f42ec UBSAN: emit distinctive traps
Sometimes people get minimal crash reports after a UBSAN incident. This change
tags each trap with an integer representing the kind of failure encountered,
which can aid in tracking down the root cause of the problem.

Rafael Espindola 922f2aa9b2 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.

Akira Hatanaka 5720be5e34 Fix test case to appease buildbot.
Test case trap-fnattr.cpp was failng on clang-ppc64-elf-linux2 because ppc64
sign-extends the i32 return value.
 
This is a follow-up to r241306.

Akira Hatanaka 85365cd72a Attach attribute "trap-func-name" to call sites of llvm.trap and llvm.debugtrap.
This is needed to use clang's command line option "-ftrap-function" for LTO and
enable changing the trap function name on a per-call-site basis.
