22bef74b55 Remove shared tydescs
All tydescs are static now, there's no need to worry about
marshalling them between threads anymore.

1c7a62c93b Use a memset upcall to zero things without static alignment
This fixes issues #843 and #1546. The cost of an upcall is
unfortunate, though. I assume there must be a way to simply manually
compute the pointer or size, using something akin to the formula in
`align_to` in `rust_util.h`. I could not get this to work,
unfortunately.

822acdd170 Make binding of fns with bounded type parameters work
Interns non-static dicts to heap-allocated equivalents so that they no
longer have stack scope.

bd6b80c972 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.

c73eb8ff51 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.
