0bcbd1df7a 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.

06e6c385cb Fix crash from r158529 on Bullet. 
Dynamic GEPs created by SROA needed to insert extra "i32 0"
operands to index through structs and arrays to get to the
vector being indexed.

c055a8782e Fix PR11106 by correcting a typo that has been in the code for over a year. This 
would have never worked, since the element type of a vector type is never a
vector type. Also fix the conditional to be more direct in checking whether
EltTy is a vector type.

2bc3d52b9a Change a bunch of isVolatile() checks to check for atomic load/store as well. 
No tests; these changes aren't really interesting in the sense that the logic is the same for volatile and atomic.

I believe this completes all of the changes necessary for the optimizer to handle loads and stores correctly.  I'm going to try and come up with some additional testing, though.

3ebb05d9a6 When scalar replacement returns a vector type, only accept it if the vector 
type's bitwidth matches the (allocated) size of the alloca. This severely
pessimizes vector scalar replacement when the only vector type being used is
something like <3 x float> on x86 or ARM whose allocated size matches a
<4 x float>.

I hope to fix some of the flawed assumptions about allocated size throughout
scalar replacement and reenable this in most cases.

of the alloca). This fixes PR10082.
