When LSR is replacing an instruction, call
...
ScalarEvolution::deleteValueFromRecords on it before doing the
replaceAllUsesWith, because ScalarEvolution looks at the instruction's
users to find SCEV references to the instruction's SCEV object in its
internal maps.
Move all of LSR's loop-related state clearing after processing the loop
and before cleaning up dead PHI nodes. This eliminates all of LSR's SCEV
references just before the calls to ScalarEvolution::deleteValueFromRecords
so that when ScalarEvolution drops its own SCEV references, the reference
counts will reach zero and the SCEVs will be deleted immediately.
These changes fix some compiler aborts involving ScalarEvolution holding
onto and reusing SCEV objects for instructions that have been deleted.
No regression test unfortunately; because the symptoms were due to
dangling pointers, reduced testcases ended up being fairly arbitrary.

Perform stricter/more accurate checking for C99 constant expressions
...
in Sema, per discussion on mailing list. This doesn't cause any changes

real code.
This doesn't touch the existing isConstantExpr method on Expr; that
should be addressed somehow eventually (either removed or refined to
whatever is appropriate).

Add a couple more headers. stddef was discussed on cfe-dev, and
...
consensus was that it was fine; iso646 is trivial.
We actually don't need that many headers overall... on Ubuntu, at least,
all we need are stdint.h, stdarg.h, limits.h, and float.h to stop
depending on having gcc's headers around for normal code.
On a side note, the path searching needs some improvement; I had to
hardcode the path to my header directory into clang.cpp to get the
driver to use it consistently.

Teach instcombine 4 new xforms:
...
(add (sext x), cst) --> (sext (add x, cst'))
(add (sext x), (sext y)) --> (sext (add int x, y))
(add double (sitofp x), fpcst) --> (sitofp (add int x, intcst))
(add double (sitofp x), (sitofp y)) --> (sitofp (add int x, y))
This generally reduces conversions. For example MiBench/telecomm-gsm
gets these simplifications:
