- New isDefined() function checks for deletedness
 - isThisDeclarationADefinition checks for deletedness
 - New doesThisDeclarationHaveABody() does what
   isThisDeclarationADefinition() used to do
 - The IsDeleted bit is not propagated across redeclarations
 - isDeleted() now checks the canoncial declaration
 - New isDeletedAsWritten() does what it says on the tin.
 - isUserProvided() now correct (thanks Richard!)

This fixes the bug that we weren't catching

void foo() = delete;
void foo() {}

as being a redefinition.

Instead of returning a pointer to the domain, we return a new copy of it. This
is safer, as we do not give access to internal objects. It is also not
expensive, as isl will just increment a reference counter.

Don't emit nsw flags for vector operations; there's basically no benefit, and a lot of downside (like PR9850, which is about clang's xmmintrin.h making an unexpected transformation on an expression involving _mm_add_epi32).

After a virtual register is split, update any debug user variables that resided
in the old register. This ensures that the LiveDebugVariables are still correct
after register allocation.

This may create DBG_VALUE instructions that place a user variable in a register
in parts of the function and in a stack slot in other parts. DwarfDebug
currently doesn't support that.

Add an implementation of thunks for varargs methods.  The implementation is a bit messy, but it is correct as long as the method in question doesn't use indirect gotos.  A couple of possible alternative implementations are outlined in FIXME's in this patch. rdar://problem/8077308 .

The post-ra scheduler was explicitly updating the depth of a node's
successors after scheduling it, regardless of whether the successor
was ready. This is quadratic for DAGs with transitively redundant
edges. I simply removed the useless update of depth, which is lazilly
computed later.

CXTranslationUnit_NestedMacroInstantiations, which indicates whether
we want to see "nested" macro instantiations (e.g., those that occur
inside other macro instantiations) within the detailed preprocessing
record. Many clients (e.g., those that only care about visible tokens)
don't care about this information, and in code that uses preprocessor
metaprogramming, this information can have a very high cost.
