100f3ac565 generalize a transformation even more: we don't care whether the 
input the the mul is a zext from bool, just that it is all zeros
other than the low bit.  This fixes some phase ordering issues
that would cause us to miss some xforms in mul.ll when the worklist
is visited differently.

ed37f33b81 LICM shouldn't sink/delete debug information. Fix this and add a testcase. 
For now the metadata of sinked/hoisted instructions is still wrong, but that'll
be fixed when instructions will have debug metadata directly attached.

601cc4c588 implement rdar://7293527, a trivial instcombine that llvm-gcc 
gets but clang doesn't, because it is implemented in GCC's
fold routine.

1832a32b78 implement a transformation in jump threading that is currently 
done by condprop, but do it in a much more general form.  The
basic idea is that we can do a limited form of tail duplication
in the case when we have a branch on a phi.  Moving the branch
up in to the predecessor block makes instruction selection
much easier and encourages chained jump threadings.

37ff3c0ed1 switch GVN to use SSAUpdater. Besides removing a lot of complexity 
from GVN, this also speeds it up, inserts fewer PHI nodes (see the
testcase) and allows it to remove more loads (due to fewer PHI nodes
standing in the way).

f2ae9c6220 Fix the x86 test-shrink optimization so that it doesn't shrink comparisons 
when one of the bits being tested would end up being the sign bit in the
narrower type, and a signed comparison is being performed, since this would
change the result of the signed comparison. This fixes PR5132.

10c870b46f When considering whether to inline Callee into Caller, 
and that will make Caller too big to inline, see if it
might be better to inline Caller into its callers instead.
This situation is described in PR 2973, although I haven't
tried the specific case in SPASS.

d47d348cdf It's possible for a global variable to be optimized out of a metadata object. So 
we should allow a "null" with this dyn_cast.
