Pete Cooper 856977cb15 DeadStoreElimination can now trim the size of a store if the end of the store is dead. 
Currently checks alignment and killing stores on a power of 2 boundary as this is likely
to trim the size of the earlier store without breaking large vector stores into scalar ones.

Fixes <rdar://problem/10140300>

Tobias Grosser e4e2f7b16e TempScop: Rename SCEVAffFunc to IRAccess 
The SCEVAffFunc is now only used to express memory accesses. Give it a proper
name and rework the class such that this is obvious.

Tobias Grosser f317e3ac83 Do not check memory accesses additionally with isValidAffineFunction 
This check was necessary because of the use AffineSCEVIterator in TempScopInfo.
As we removed this use recently it is not necessary any more.

Sean Callanan 0730e9c992 Added a function to ClangASTSource to service 
lookups for Objective-C methods by selector.
Right now all it does is print log information.

Also improved the logging for imported TagDecls
to indicate whether or not the definition for
the imported TagDecl is complete.

Duncan Sands 635e4efca0 Speculatively revert commit 144124 (djg) in the hope that the 32 bit 
dragonegg self-host buildbot will recover (it is complaining about object
files differing between different build stages).  Original commit message:

Add a hack to the scheduler to disable pseudo-two-address dependencies in
basic blocks containing calls. This works around a problem in which
these artificial dependencies can get tied up in calling seqeunce
scheduling in a way that makes the graph unschedulable with the current
approach of using artificial physical register dependencies for calling
sequences. This fixes PR11314.

Wojciech Matyjewicz 0c48772aaa Minor fixes in Makefiles for the OCaml bindings: 
1. Interface files (.mli) are installed before compiled interface
   files (.cmi) to preserve timestamp relation.
2. install-meta should use $(OcamlDir) instead of $(ObjDir).
3. Declared some targets as .PHONY.

Patch by Christophe Raffalli.

Jason Molenda 3dc8583c96 Remove the QAddressIsExecutable packet I added last night. 
Add a more general purpose qMemoryRegionInfo packet which can
describe various attributes about a memory region.  Currently it
will return the start address, size, and permissions (read, write,
executable) for the memory region.  It may be possible to add
additional attributes in the future such as whether the region is
designated as stack memory or jitted code a la vmmap.

I still haven't implemented the lldb side of the code to use this
packet yet so there may be unexpected behavior - but the basic implementation looks
about right.  I'll hook it up to lldb soon and fix any problems that crop up.
