Instantiate exception specifications when instantiating function types (other
than the type of a function declaration). We previously didn't instantiate
these at all! This also covers the pathological case where the only mention of
a parameter pack is within the exception specification; this gives us a second
way (other than alias templates) to reach the horrible state where a type
contains an unexpanded pack, but its canonical type does not.

Sema: Diagnose undefined structs used as Microsoft anonymous structs

Previously, we would not mark structs containing anonymous structs as
invalid.  Later, horrific things would occur when trying to determine
the size of the parent record.

Instead, require the struct to be a complete type when used as an
anonymous struct.  Mark both the anonymous field for the struct and the
parent context as invalid (this is similar to what we do when a struct
contains a field with an incomplete type.)

This fixes PR11847.

Change -Wbind-to-temporary-copy from an ExtWarn to an Extension.

The reasoning is that this construct is accepted by all compilers and valid in
C++11, so it doesn't seem like a useful warning to have enabled by default.
Building with -pedantic, -Wbind-to-temporary-copy, or -Wc++98-compat still
shows the warning.

The motivation is that I built re2, and this was the only warning that was
emitted during the build. Both changing re2 to fix the warning and detecting
clang and suppressing the warning in re2's build seem inferior than just giving
the compiler a good default for this warning.

Also move the cxx98compat version of this warning to CXX98CompatPedantic, and
update tests accordingly.

The Windows build was broken for 16 hours and no one had any good ideas of how to
fix it. Reverting for now to make the builders green. See the cfe-commits thread [1] for
more info.

This was the build error (from [2]):
