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.

Closes #1436

295df68faf add alignment to i386 for good measure, though we do not yet
save SSE regs in i386 (we ought to, though!)

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.

fe683dfb80 rt: Get rid of the valgrind guard bytes at the end of the 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.

7d51961b6f 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.
