is-function-local flag in metadata uniquing bits.

04d6c289ab Remove NEON vaddl, vaddw, vsubl, and vsubw intrinsics. Instead, use llvm 
IR add/sub operations with one or both operands sign- or zero-extended.
Auto-upgrade the old intrinsics.

7548fb37f1 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.

55ae515f9d 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).

489b29b0a4 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.

65bffec2c2 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.

certainly a mistake.

b08ba8824e 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.
