Cherry-pick LLVM 187787 to prevent tail calls on x86-32 when not appropriate.
See:
http://llvm.org/viewvc/llvm-project?view=revision&revision=187787
The newer version of newlib tickles this x86-32 bug
when building the exception handling tests, which don't
strip the "tail" attribute.
BUG=https://code.google.com/p/nativeclient/issues/detail?id=3702
Waiting on trybots, but it seems to have fixed the minimal
