323d8c3ed7 Be more clever about calculating live variables through new basic blocks.
When splitting a critical edge, the registers live through the edge are:

- Used in a PHI instruction, or
- Live out from the predecessor, and
- Live in to the successor.

This allows the coalescer to eliminate even more phi joins.

a58a04921d Make Loop::getLoopLatch() work on loops which don't have preheaders, as
it may be used in contexts where preheader insertion may have failed due

Make LoopSimplify's LoopSimplify::SeparateNestedLoop properly fail in
the case that it would require splitting an indirectbr edge.

a9562568e5 The verify() call of CPEIsInRange() isn't right for the assertion check of
constant pool ranges, as CPEIsInRange() makes conservative assumptions about
the potential alignment changes from branch adjustments. The verification,
on the other hand, runs after those branch adjustments are made, so the
effects on alignment are known and already taken into account. The sanity
check in verify should check the range directly instead.

837be07979 Revert the rule that considers comparisons between two pointers in the
same object to be a non-capture; Duncan pointed out a way that such
a comparison could be a capture.

Make the rule that considers a comparison against null more specific,
and only consider noalias return values compared against null. This
still supports test/Transforms/GVN/nonescaping-malloc.ll, and is not
susceptible to the problem Duncan pointed out with noalias arguments.

37628e0098 Move the handling of CommaSeparated options into ProvideOption.
Makes '--comma-separated val1,val2' mean the same thing as
'--comma-separated=val1,val2' (that is, 'val1' and 'val2' are not lumped
together as 'val1,val2'). Also declutters the main loop a bit.

76700ba64c Fix PR5563, an expensive checks failure when running on
tests/Transforms/InstCombine/shufflemask-undef.ll.  If
anyone cares, the use of 2*e here (and the equivalent
all over the place in instcombine) seems wrong, though
harmless: it should really be twice the length of the
input vector.  I think shufflevector used to require
that the mask have the same length as the input, but I
don't think that's true any more.  I don't care enough
about vectors to do anything about this...
