af33b7b4a7 The lower invoke pass needs to have unreachable code elimination run after it 
because it could create such things. This fixes a MingW buildbot test failure.

3dcc91ee8c The two-callsite form of AliasAnalysis::getModRefInfo is documented 
to return Ref if the left callsite only reads memory read or written
by the right callsite; fix BasicAliasAnalysis to implement this.

Add AliasAnalysisEvaluator support for testing the two-callsite
form of getModRefInfo.

1a0f91b7c5 Coalesce stack slot accesses that arise when spilling both sides of a COPY. 
This helps avoid silly code:

    STORE <fi#5>, %R0<kill>

936ed5424c Reserve a stack slot if the function adjusts the stack but doesn't 
simplify the call frame pseudo instructions. In that situation, the
calculations for estimating the stack size will be way off, leading to
not having an emergency spill slot when we need one. It should be possible
to be more precise about tracking the adjustment values, but not really
necessary for correctness. Upcoming cleanups for PEI in general will
render that moot.

loops, although still with some bugs.

0e3a1a8f8f Use indirect calls in PowerPC JIT. 
See PR5201. There is no way to know if direct calls will be within the allowed
range for BL. Hence emit all calls as indirect when in JIT mode.
Without this long-running applications will fail to JIT on PowerPC with a
relocation failure.

c575283675 Print an error message when someone tries -integrated-as on an unsupported target. 
- The COFF backend doesn't support MingW/Cygwin at the moment, it'll report an
  error, but it's still much better than random assertions from the MachO backend.
- We want to make ELF the default eventually, it's what the majority of targets use.

"The CWriter::GetValueName() method does not check if a value as an alias 
and emits the alias name which will never be defined in the output .c 
file (so the output file fails to compile). This can happen if you have 
multiple inheritance with several destructors defined by clang (...D0Ev, 
...D1Ev, ...D2Ev)."
