If a ParmVarDecl's default argument is a CXXExprWithTemporaries, return the underlying expr instead. Add getNumDefaultArgTemporaries and getDefaultArgTemporary which returns the temporaries a default arg creates.

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.

want some clients of QualType to think it's a pod and some to 
not know it is.

llvm-svn: 91424

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.

note_previous_decl was used where note_previous_declaration was intended. Better
names or PR5785 might be nice.

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

pointers for the noreturn attribute when checking for fallthrough.

We creating and free thousands of MacroArgs objects (and the related
std::vectors hanging off them) for the testcase in PR5610 even though
there are only ~20 live at a time.  This doesn't actually use the 
cache yet.

now, don't construct CFGs that contain C++ try/catch statements, and
have GRExprEngine abort a path if it encounters a C++ construct it
doesn't understand (which is mostly everything at this point).
