Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

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.

update to match LLVM API change:
Remove isPod() from DenseMapInfo, splitting it out to its own
isPodLike type trait. This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

This patch should fix PR2461. It allows clang to apply the noreturn
attribute to function pointers. It also fixes Sema to check function
pointers for the noreturn attribute when checking for fallthrough.

Improve template instantiation for object constructions in several ways:
- 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."

Rework the way we handle template instantiation for
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.
