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

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.

9a738fd61d rt: Various tweaks to make __morestack unwinding work on linux
When unwinding through __morestack the stack limit in the TLS is invalidated
and must be reset. Instead of actually landing at __morestack we're
just going to make all our Rust landing pads call upcall_reset_stack_limit,
which will find the stack segment that corresponds to the current stack
pointer and put the limit in the TLS.

Also massively expand the stack segment red zone to make more room for the
dynamic linker. Will fix in the future.

8124846b2c Get rid of taskpointer-passing throughout the compiler
Only intrinsics still take a dummy taskptr. We'll have to do some
makefile stunts to snapshot a version without taskptrs-in-intrinsics.
