aefb0f06a9 ARM tidy up ARMConstantIsland.cpp. 
No functional change, just tidy up the code and nomenclature a bit.

ef28237798 Don't convert objc_retainAutoreleasedReturnValue to objc_retain if it 
is retaining the return value of an invoke that it immediately follows.

0c02608af1 It's not possible to insert code immediately after an invoke in the 
same basic block, and it's not safe to insert code in the successor
blocks if the edges are critical edges. Splitting those edges is
possible, but undesirable, especially on the unwind side. Instead,
make the bottom-up code motion to consider invokes to be part of
their successor blocks, rather than part of their parent blocks, so
that it doesn't push code past them and onto the edges. This fixes
PR12307.

7da86bf59f Make it feasible for clients using EngineBuilder to capture the TargetMachine that is created as part of selecting the appropriate target. 
This is necessary if the client wants to be able to mutate TargetOptions (for example, fast FP math mode) after the initial creation of the ExecutionEngine.

fcc4791c7b When propagating equalities, eg replacing A with B in every basic block 
dominated by Root, check that B is available throughout the scope.  This
is obviously true (famous last words?) given the current logic, but the
check may be helpful if more complicated reasoning is added one day.

11cd3dd9fc Take out the debug info probe stuff. It's making some changes to 
the PassManager annoying and should be reimplemented as a decorator
on top of existing passes (as should the timing data).

8243f2a6d4 Revert a series of commits to MCJIT to get the build working in CMake 
(and hopefully on Windows). The bots have been down most of the day
because of this, and it's not clear to me what all will be required to
fix it.

The commits started with r153205, then r153207, r153208, and r153221.
The first commit seems to be the real culprit, but I couldn't revert
a smaller number of patches.

When resubmitting, r153207 and r153208 should be folded into r153205,
they were simple build fixes.

ce3a78be60 [fast-isel] Fold "urem x, pow2" -> "and x, pow2-1". This should fix the 271% 
execution-time regression for nsieve-bits on the ARMv7 -O0 -g nightly tester.
This may also improve compile-time on architectures that would otherwise 
generate a libcall for urem (e.g., ARM) or fall back to the DAG selector.
