The thread_info changes over the life of the thread, so you can't get it once and cache it, you have to fetch it every time you want to use it.

non-class prvalues actually require the realization of a

prvalue) in the subexpression.

Note: we're missing some move elision in this case. I'll tackle that next.

access control errors into SFINAE errors, so that the trait provides
enough support to implement the C++0x std::is_convertible type trait.

To get there, the SFINAETrap now knows how to set up a SFINAE context
independent of any template instantiations or template argument
deduction steps, and (separately) can set a Sema flag to translate
access control errors into SFINAE errors. The latter can also be
useful if we decide that access control errors during template argument
deduction should cause substitution failure (rather than a hard error)
as has been proposed for C++0x.

rdar://problem/8893967: JM/lencod miscompile at -arch armv7 -mthumb -O3

Added ResurrectKill to remove kill flags after we decide to reused a
physical register. And (hopefully) ensure that we call it in all the
right places.

Sorry, I'm not checking in a unit test given that it's a miscompile I
can't reproduce easily with a toy example. Failures in the rewriter
depend on a series of heuristic decisions maked during one of the many
upstream phases in codegen. This case would require coercing regalloc
to generate a couple of rematerialzations in a way that causes the
scavenger to reuse the same register at just the wrong point.

The general way to test this is to implement kill flags
verification. Then we could have a simple, robust compile-only unit
test. That would be worth doing if the whole pass was not about to
disappear. At this point we focus verification work on the next
generation of regalloc.

Reverted previous fix to is_convertible as it caused more problems than it fixed.  But this reverted fix will only matter for non-clang compilers.  Installed __is_convertible_to for clang.

semantics after the C++0x is_convertible type trait. This
implementation is not 100% complete, because it allows access errors
to be hard errors (rather than just evaluating false).
