36fa5321ba Fix another problem with ARM constant pools. Radar 7303551. 
When ARMConstantIslandPass cannot find any good locations (i.e., "water") to
place constants, it falls back to inserting unconditional branches to make a
place to put them.  My recent change exposed a problem in this area.  We may
sometimes append to the same block more than one unconditional branch.  The
symptoms of this are that the generated assembly has a branch to an undefined
label and running llc with -debug will cause a seg fault.

This happens more easily since my change to prevent CPEs from moving from
lower to higher addresses as the algorithm iterates, but it could have
happened before.  The end of the block may be in range for various constant
pool references, but the insertion point for new CPEs is not right at the end
of the block -- it is at the end of the CPEs that have already been placed
at the end of the block.  The insertion point could be out of range.  When
that happens, the fallback code will always append another unconditional
branch if the end of the block is in range.

The fix is to only append an unconditional branch if the block does not
already end with one.  I also removed a check to see if the constant pool load
instruction is at the end of the block, since that is redundant with
checking if the end of the block is in-range.

There is more to be done here, but I think this fixes the immediate problem.

2ee743b53b only try to fold constantexpr operands when the worklist is first populated, 
don't bother every time going around the main worklist.  This speeds up a 
release-asserts opt -std-compile-opts on 403.gcc by about 4% (1.5s).  It
seems to speed up the most expensive instances of instcombine by ~10%.

e2cc1ad230 don't bother calling ConstantFoldInstruction unless there is a use of the 
instruction (which disqualifies stores, unreachable, etc) and at least the
first operand is a constant.  This filters out a lot of obvious cases that
can't be folded.  Also, switch the IRBuilder to a TargetFolder, which tries
harder.

only dereference the element they point to directly with no pointer arithmetic.

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.

b01bbdcc1a I don't see any point in having both eh.selector.i32 and eh.selector.i64, 
so get rid of eh.selector.i64 and rename eh.selector.i32 to eh.selector.
Likewise for eh.typeid.for.  This aligns us with gcc, which always uses a
32 bit value for the selector on all platforms.  My understanding is that
the register allocator used to assert if the selector intrinsic size didn't
match the pointer size, and this was the reason for introducing the two
variants.  However my testing shows that this is no longer the case (I
fixed some bugs in selector lowering yesterday, and some more today in the
fastisel path; these might have caused the original problems).

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.
