rt: Get rid of the rethrow in upcall_fail
...
Throwing in upcall_fail ends up running lots of code in the red zone. To avoid
it we have the personality function figure out which stack it's on and switch
as needed.

rt: Create different stack-switching paths for upcalls and shims
...
Shims need to play with the stack limit, upcalls don't. Only one upcall,
upcall_fail is allowed to catch, and we need a find a way to get rid of that
catch as well because it results in _Unwind_Resume running off the end of the
Rust stack.

Preventing us from writing beyond our allocations is _what valgrind does_,
so telling valgrind not to let us write to the end of the stack isn't
buying anything.

rt: Fix saved address of unwinding %rsp in __morestack

I haven't thought too deeply about this, but I think I was telling the
unwinder to use the stack pointer for the wrong frame when unwinding. Not sure
how that could have worked at all, but this results in the correct alignment
for cleanups.
