8db2cd1fc7 make instcombine's instruction sinking more aggressive in the 
presence of PHI nodes.

681a33e26d Another BasicAA fix. If a value does not alias a GEP's base pointer, then it 
cannot alias the GEP. GEP pointer alias rule states this clearly:
A pointer value formed from a getelementptr instruction is associated with the
addresses associated with the first operand of the getelementptr.

11f15dbb28 change simplifycfg to not duplicate 'unwind' instructions. Hopefully 
this will increase the likelihood of common code getting sunk towards
the unwind.

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.

test it, using FileCheck.

d2c58366d8 generalize a transformation even more: we don't care whether the

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.
