3348d2eb50 Remove NEON vmull, vmlal, and vmlsl intrinsics, replacing them with multiply, 
add, and subtract operations with zero-extended or sign-extended vectors.
Update tests.  Add auto-upgrade support for the old intrinsics.

807d004452 Remove NEON vaddl, vaddw, vsubl, and vsubw intrinsics. Instead, use llvm 
IR add/sub operations with one or both operands sign- or zero-extended.

c01101e76c Add alignment arguments to all the NEON load/store intrinsics. 
Update all the tests using those intrinsics and add support for
auto-upgrading bitcode files with the old versions of the intrinsics.

6e1e480f13 Don't include the is-function-local bit in the FoldingSetNodeID 
for MDNodes, since this information is effectively implied by
the operands. This allow allows the code to avoid doing a
recursive is-it-really-function-local check in some cases.

163660135e Create the new linker type "linker_private_weak_def_auto". 
It's similar to "linker_private_weak", but it's known that the address of the
object is not taken. For instance, functions that had an inline definition, but
the compiler decided not to inline it. Note, unlike linker_private and
linker_private_weak, linker_private_weak_def_auto may have only default
visibility.  The symbols are removed by the linker from the final linked image
(executable or dynamic library).

072e7bdcd4 Introduce a new temporary MDNode concept. Temporary MDNodes are 
not part of the IR, are not uniqued, and may be safely RAUW'd.
This replaces a variety of alternate mechanisms for achieving
the same effect.

b09e2e1be4 Make dumpPassStructure be a PMDataManager abstraction, rather than 
a Pass abstraction, since that's the level it's actually used at.
Rename Pass' dumpPassStructure to dumpPass.

This eliminates an awkward use of getAsPass() to convert a PMDataManager*
into a Pass* just to permit a dumpPassStructure call.

939744be5f Define a maximum supported alignment value for load, store, and 
alloca instructions (constrained by their internal encoding),
and add error checking for it. Fix an instcombine bug which
generated huge alignment values (null is infinitely aligned).

816457c7f3 After updating value handles for RAUW, check that no weak or tracking handles 
are still on the list.  This might happen if a CallbackVH created some new value
handles for the old value when doing RAUW.  Barf if it occurs, since it is almost
certainly a mistake.

e191a19b69 Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock: 
don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.

Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.

This fixes a major compile-time bottleneck which is exposed now that
LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.
