Clean up the tests for warning about unused function results given the
...
appropriate attribute. Add a bit more testing that finds a pretty bad
regression (since ~forever) in this warning. Fix it with a nice 2 line
change. =]

Do not use CXXZeroValueInitExpr for class types. Instead, use
...
CXXConstructExpr/CXXTemporaryObjectExpr/CXXNewExpr as
appropriate. Fixes PR7556, and provides a slide codegen improvement
when copy-initializing a POD class type from a value-initialized
temporary. Previously, we weren't eliding the copy.

When we have a dependent direct initializer but not a dependent
...
variable type, we can (and should) still check for completeness of the
variable's type. Do so, to work around an assertion that shows up in
Boost's shared_ptr.
