For hi/odd of an odd-length vector, the last component is undefined.  Since
we shuffle with an undef vector, no CodeGen needs to change to support this.

Until we can make the dead stores checker smarter, dont' emit dead store warnings for C++ objects (whose constructors/destructors have possible side-effects).

  - During instantiation, drop default arguments from constructor and
    call expressions; they'll be recomputed anyway, and we don't want
    to instantiate them twice.
  - Rewrote the instantiation of variable initializers to cope with
    non-dependent forms properly.

Together, these fix a handful of problems I introduced with the switch
to always rebuild expressions from the source code "as written."

implicitly-generated AST nodes. We previously built instantiated nodes
for each of these AST nodes, then passed them on to Sema, which was
not prepared to see already-type-checked nodes (see PR5755). In some
places, we had ugly workarounds to try to avoid re-type-checking
(e.g., in VarDecl initializer instantiation).

Now, we skip implicitly-generated nodes when performing instantiation,
preferring instead to build just the AST nodes that directly reflect
what was written in the source code. This has several advantages:

  - We don't need to instantiate anything that doesn't have a direct
    correlation to the source code, so we can have better location
    information.
  - Semantic analysis sees the same thing at template instantiation
    time that it would see for a non-template.
  - At least one ugly hack (VarDecl initializers) goes away.

Fixes PR5755.
