A minor tweak to the new volatile lvalue warning: don't warn on "(void)x", where "x" refers to a local variable. This should silence a useless warning in compiler-rt and other places.

fix Bug 12924
...
http://llvm.org/bugs/show_bug.cgi?id=12924
This issue was that the source location was pointing to a
non-printable character and so CaretEnd was pointing one
_column_ past the caret but not one _character_ past the
caret. So the conversion between column and byte locations
wasn't working (because the conversion is only valid from
the first column or byte of a character).

DR1152 / PR12931 / PR6177: A candidate function which requires binding a const

volatile reference to a temporary is not viable. My interpretation is that
DR1152 was a bugfix, not a rule change for C++11, so this is not conditional on
the language mode. This matches g++'s behavior.

Add a warning to diagnose statements in C++ like "*(volatile int*)x;". Conceptually, this is part of -Wunused-value, but I added a separate flag -Wunused-volatile-lvalue so it doesn't get turned off by accident with -Wno-unused-value. I also made a few minor improvements to existing unused value warnings in the process. <rdar://problem/11516811>.

Correct the starting location for instantiations of field declarations which

start with a cv-qualifier. DeclaratorDecl::getTypeSpecStartLoc() does not
produce the location of the first type-specifier (the cv-qualifier) in this
case, because we don't track source locations for cv-qualifiers.
No test here: I've not found a way to test this with a lit-style test, and
introducing a gtest test for this seems unwarranted. Suggestions welcome!

template <class P>
struct bar {

template <>
struct bar<foo> {

void bar<foo>::zed() {

But adding HIDDEN to the specialization would cause us to produce a default
