a1beca6845 Apply the patch from PR14160. I failed to construct a testcase for this, but
I'm applying it anyway since it seems to be obviously correct.

2578c123f0 Fix the IntegersSubsetTest unit test when compiled with gcc-4.7. The issue here
is that the unit test doesn't have IntTy equal to APInt, instead it uses a class
derived from APInt.  When, as in these lines, an IntTy& reference is returned
but is assigned to an APInt&, the compiler destroys the temporary the IntTy& was
referring to, leaving the APInt& referring to garbage.  This causes the unittest
to fail systematically on my machine; it can also be caught by running the test
under valgrind.

a307a1cf85 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.

a864748284 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.

9b25ff66dd PGO: allows the profile data file name to be specified by the LLVMPROF_OUTPUT
environment variable.

This allows parallel make for profiling code, without it there are file
collisions as each parallel run uses the default file name.

There is already code in the runtime library to specify the output file name
via the command line, but this only works for programs which already process
argc/argv.  This patch builds on that support.

When target cost information is available, compute explicit costs of inserting and
extracting values from vectors. At this point, all costs are estimated using the
target information, and the chain-depth heuristic is not needed. As a result, it is now, by
default, disabled when using target costs.

174fbec3df Add a getAddressSpace method to the GEP instruction to mirror that of
the inttoptr instruction. The conceptual model here is that
'getAddressSpace' refers to the address space of this instruction's
type. It just happens that for GEPs, that is always the same as the
pointer operand's address space. We want both names so that access
patterns can be consistent between different instruction types.
