fef02427cd 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.

cd6f46e2ac 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.

28b7c7feab 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.

892aaf8d74 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).

03fa6ea402 - When performing pre-/post- indexed load/store transformation, do not worry

  address pass split it back to non-indexed ops.
