New Revision: 169409

URL: http://llvm.org/viewvc/llvm-project?rev=169409&view=rev
Backed out part of the ABI changes that were checked in because it breaks the i386 test suite as it makes backtraces for the first instruction of a function fail. Stepping relies on backtraces being correct, so I am reverting what is causing the breakage.

I filed this to track the fix:

<rdar://problem/12817918> Recent i386 ABI changes break the i386 test suite because stack backtracing is busted when stopped in trampolines
