b00f236b03 Move zext and sext casts fed by loads into the same block as the 
load, to help SelectionDAG fold them into the loads, unless
conditions are unfavorable.

cd2ae14ce3 Make CodePlacementOpt align loops, rather than loop headers. The 
header is just the entry block to the loop, and it needn't be at
the top of the loop in the code layout.

Remove the code that suppressed loop alignment for outer loops,
so that outer loops are aligned.

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.

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.
