Dan Gohman 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.

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

    %R0<def = LOAD <fi#5>
    STORE <fi#5>, %R0<kill>

Jim Grosbach 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.

Torok Edwin 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.

Gabor Greif ac27ec0f5b by Alexander Herz:
"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)."
