analysis passes are not prepared to be used interprocedurally.

47e6a5f906 extend ArgOperand interface: setArgOperand 
(in both CallInst and InvokeInst)

also add a (short-lived) constant to CallInst, that names
the operand index of the first call argument. This is
strictly transitional and should not be used for new code.

d3a1ef7fea minor cleanup to SROA: when lowering type unsafe accesses to 
large integers, the first inserted value would always create
an 'or X, 0'.  Even though this is trivially zapped by
instcombine, don't bother creating this pointless instruction.

68f39e00a4 Fix PR7328: when turning a tail recursion into a loop, need to preserve 
the returned value after the tail call if it differs from other return
values.  The optimal thing to do would be to introduce a phi node for
the return value, but for the moment just fix the miscompile.

6ee6192312 Clean up some problems with extra CFG edges being introduced during 
if-conversion.  The RemoveExtraEdges function doesn't work for blocks that
end with unanalyzable branches, so in those cases, the "extra" edges must
be explicitly removed.  The CopyAndPredicateBlock and MergeBlocks methods
can also avoid copying successor edges due to branches that have already
been removed.  The latter case is especially helpful when MergeBlocks is
called for handling "diamond" if-conversions, where otherwise you can end
up with some weird intermediate states in the CFG.  Unfortunately I've
been unable to find cases where this cleanup actually makes a significant
difference in the code.  There is one test where we manage to remove an
empty block at the end of a function.  Radar 6911268.

6dee31aa07 When creating X86 MUL8 and DIV8 instructions, make sure we don't produce 
CopyFromReg nodes for aliasing registers (AX and AL). This confuses the fast
register allocator.

Instead of CopyFromReg(AL), use ExtractSubReg(CopyFromReg(AX), sub_8bit).

This fixes PR7312.

c0c37cea64 Thumb2ITBlockPass: Fix a possible dereference of an invalid iterator. This was 
introduced in r106343, but only showed up recently (with a particular compiler &
linker combination) because of the particular check, and because we have no
builtin checking for dereferencing the end of an array, which is truly
unfortunate.

71ad56676d Don't track kills in VNInfo. Use interval ends instead. 
The VNInfo.kills vector was almost unused except for all the code keeping it
updated. The few places using it were easily rewritten to check for interval
ends instead.

The two new methods LiveInterval::killedAt and killedInRange are replacements.

This brings us down to 3 independent data structures tracking kills.
