7c277da364 Add a new optimization pass: Stack Coloring, that merges disjoint static allocations (allocas). Allocas are known to be 
disjoint if they are marked by disjoint lifetime markers (@llvm.lifetime.XXX intrinsics).

505715d816 Add SelectionDAG::getTargetIndex. 
This adds support for TargetIndex operands during isel. The meaning of
these (index, offset, flags) operands is entirely defined by the target.

e38859dc8e Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp and 
include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h.

The reasoning is because the DebugInfo module is simply an interface to the
debug info MDNodes and has nothing to do with analysis.

dfab443ae8 Define a new intrinsic, @llvm.debugger. It will be similar to __builtin_trap(), 
but it generates int3 on x86 instead of ud2.

No functionality change.
