placement 'operator delete', even if there are no placement args (i.e.
overload resolution selected an operator new with default arguments).

The canonical FunctionTemplateDecl contains the specializations but we cannot use getCanonicalDecl on Template because it may still be initializing.
Write and read it from PCH.

sequences for two conversion functions when in fact we are in the text
of initialization by a user-defined conversion sequences. Fixes PR8034.

error to a warning if we're in a case that would be allowed in
C++0x. This "fixes" PR8084 by making Clang accept more code than GCC
and (non-strict) EDG do.
Also, add the missing test case for the C++0x semantics, which should
have been in r113717.

be a semantic requirement that a built-in overloaded operator is not
added to the overload set of there is already a user-defined
overloaded operator with the same parameter types. Fixes PR8087.

declarations in potentially-evaluated subexpressions, about
recursion. Fixes the release-mode self-host failure I introduced in
r113700.

used in the default function argument as "used". Instead, when we
actually use the default argument, make another pass over the
expression to mark any used declarations as "used" at that point. This
addresses two kinds of related problems:
1) We were marking some declarations "used" that shouldn't be,
because we were marking them too eagerly.
2) We were failing to mark some declarations as "used" when we
should, if the first time it was instantiated happened to be an
unevaluated context, we wouldn't mark them again at a later point.
I've also added a potentially-handy visitor class template
EvaluatedExprVisitor, which only visits the potentially-evaluated
subexpressions of an expression. I bet this would have been useful for
noexcept...
Fixes PR5810 and PR8127.

preambles end up leaving the precompiled preambles around. This is by
design, since we do minimal cleanup during crash recovery. However,
it's unfortunate for testing, so introduce a hook that allows these
two tests to put the precompiled preamble somewhere where we can
delete them after testing.

just abort creation of the precompiled preamble rather than doing
silly things. This is the second part of the fix for the weird
preamble-related failures on Windows. Big thanks to Francois Pichet
for the great detective work!

Windows GetTempPath() function, and be sure to create the directory in
which the precompiled preamble will reside before creating the
temporary file itself.

information when imported variable is used
more than once. Originally though to be a bug in importing
block varibles. Fixes radar 8417746.
