Andrew Kaylor fb05a50f6b Change resolveRelocation parameters so the relocations can find placeholder values in the original object buffer. 
Some ELF relocations require adding the a value to the original contents of the object buffer at the specified location.  In order to properly handle multiple applications of a relocation, the RuntimeDyld code should be grabbing the original value from the object buffer and writing a new value into the loaded section buffer.  This patch changes the parameters passed to resolveRelocations to accommodate this need.

Sean Callanan 5540094ccd Extra safeguards to ensure that we never query 
the runtime if we have complete debug information
for a class.

Also made the Objective-C language runtime return
NULL when asked for the complete debug information
(i.e., information from DWARF, not information from
the runtime) if that information isn't present.  It
used to return a non-authoritative version, which
made it hard for clients to determine whether
complete debug information was available.

Chandler Carruth b62807a95c Add a testcase to loop-idiom to cover PR14241 when we start handling 
strided loops again.

Chandler Carruth 099f5cb031 Revert the switch of loop-idiom to use the new dependence analysis. 
The new analysis is not yet ready for prime time. It has a *critical*
flawed assumption, and some troubling shortages of testing. Until it's
been hammered into better shape, let's stick with the working code. This
should be easy to revert itself when the analysis is ready.

Fixes PR14241, a miscompile of any memcpy-able loop which uses a pointer
as the induction mechanism. If you have been seeing miscompiles in this
revision range, you really want to test with this backed out. The
results of this miscompile are a bit subtle as they can lead to
downstream passes concluding things are impossible which are in fact
possible.

Thanks to David Blaikie for the majority of the reduction of this
miscompile. I'll be checking in the test case in a non-revert commit.

Revesions reverted here:

r167045: LoopIdiom: Fix a serious missed optimization: we only turned
         top-level loops into memmove.
r166877: LoopIdiom: Add checks to avoid turning memmove into an infinite
         loop.
r166875: LoopIdiom: Recognize memmove loops.
r166874: LoopIdiom: Replace custom dependence analysis with
         DependenceAnalysis.
