Sema::ActOnUninitializedDecl over to InitializationSequence (with
default initialization), eliminating redundancy. More importantly, we
now check that a const definition in C++ has an initilizer, which was
an #if 0'd code for many, many months. A few other tweaks were needed
to get everything working again:

  - Fix all of the places in the testsuite where we defined const
    objects without initializers (now that we diagnose this issue)
  - Teach instantiation of static data members to find the previous
    declaration, so that we build proper redeclaration
    chains. Previously, we had the redeclaration chain but built it
    too late to be useful, because...
  - Teach instantiation of static data member definitions not to try
    to check an initializer if a previous declaration already had an
    initializer. This makes sure that we don't complain about static
    const data members with in-class initializers and out-of-line
    definitions.
  - Move all of the incomplete-type checking logic out of
    Sema::FinalizeDeclaratorGroup; it makes more sense in
    ActOnUnitializedDecl.

There may still be a few places where we can improve these
diagnostics. I'll address that as a separate commit.

IRgen: Add CreateMemTemp, for creating an temporary memory object for a particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing.

- This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome!

Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

Initial skeleton and SCEVUnknown lowering implemented,
the rest should come relatively quickly.  Move testcase
to new directory.

Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.
