David Majnemer 958f6288ef AST: Update reference temporary mangling
Summary:
Update our mangling to match the discussion on cxx-abi-dev.

This involves using a seq-id instead of an optional number.

David Majnemer a9cf72f94d CodeGen: Assign linkage to thread-wrappers correctly
We would sometimes incorrectly give a thread-wrapper external linkage
instead of internal linkage if we had only CodeGen'd it's declaration,
not it's definition.

This fixes PR19655.

David Majnemer f5563f5736 CodeGen: Fix linkage of reference temporaries
Summary:
A reference temporary should inherit the linkage of the variable it
initializes.  Otherwise, we may hit cases where a reference temporary
wouldn't have the same value in all translation units.

Richard Smith 8a07cd3f59 Reapply r183721, reverted in r183776, with a fix for a bug in the former (we
were lacking ExprWithCleanups nodes in some cases where the new approach to
lifetime extension needed them).

Original commit message:

Rework IR emission for lifetime-extended temporaries. Instead of trying to walk
into the expression and dig out a single lifetime-extended entity and manually
pull its cleanup outside the expression, instead keep a list of the cleanups
which we'll need to emit when we get to the end of the full-expression. Also
emit those cleanups early, as EH-only cleanups, to cover the case that the
full-expression does not terminate normally. This allows IR generation to
properly model temporary lifetime when multiple temporaries are extended by the
same declaration.

We have a pre-existing bug where an exception thrown from a temporary's
destructor does not clean up lifetime-extended temporaries created in the same
expression and extended to automatic storage duration; that is not fixed by
this patch.

Richard Smith a57be5617a Revert r183721. It caused cleanups to be delayed too long in some cases.
Testcase to follow.

Richard Smith 04e5176505 CodeGen support for function-local static thread_local variables with
non-constant constructors or non-trivial destructors. Plus bugfixes for
thread_local references bound to temporaries (the temporaries themselves are
lifetime-extended to become thread_local), and the corresponding case for
std::initializer_list.
