fbab4a8c8a 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.

8e1fc56b24 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.

e959f7e17f 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.

3e29671cca 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.
