ae15a1f88d completely revert patrick's enhancement to bugpoint. Though it makes bugpoint 
speed up, it sometimes makes it crash on complex bc files, which isn't very nice.


With this, bugpoint can reduce the 176.gcc failure.

3488208b8e add a new bugpoint mode -llc-safe. This uses LLC for both halves of a 
miscompilation.  This is useful for working around GCC+CBE bugs or for handling
programs that CBE doesn't support (e.g. inline asm) when searching for
optimizer bugs.

dbb1ac36fa Add a utility script to find a mis-optimization problem. This sometimes 
helps when bugpoint can't find the problem directly because it needs the
set of optimizations that cause the program to fail.

6921c1c0a7 Divide select methods into groups by SelectionDAG node opcodes (ISD::ADD, 
X86ISD::CMP, etc.) instead of SDNode names (add, x86cmp, etc). We now allow
multiple SDNodes to map to the same SelectionDAG node (e.g. store, indexed
store).

1f5c4a6c43 - When performing pre-/post- indexed load/store transformation, do not worry 
about whether the new base ptr would be live below the load/store. Let two
  address pass split it back to non-indexed ops.

da1f5b882a For PR950: 
This patch converts the old SHR instruction into two instructions,
AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not
dependent on the sign of their operands.
