5c9be67cff Teach BasicAA a little something about the atomic intrinsics: they can only 
modify through the pointer they're given.

cc271861da Add new "memory use marker" intrinsics. These indicate lifetimes and invariant 
sections of memory objects.

5c78736f85 Memory dependence analysis was incorrectly stopping to scan for stores to a pointer at bitcast uses of a malloc call. 
It should continue scanning until the malloc call, and this patch fixes that.

f1787b055c allow this testcase to pass with recent changes. The test hasn't been 
producing any stores at all for a long time, but ".store." was in some
IR instruction names until recently.  This removal caused the test to
start failing.  Just make it reject any stores.

0032681424 Don't forget to mark RAX as live-out of the function when arranging for 
it to hold the address of an sret return value, for x86-64 ABI purposes.

Also, fix the test that was originally intended to test this to actually
test it, using FileCheck.

d2c58366d8 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.

For now the metadata of sinked/hoisted instructions is still wrong, but that'll
be fixed when instructions will have debug metadata directly attached.

78c552ef30 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.

a09fbf0af0 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).
