mips: simplify finish function
...
- Don't bother allocating any extra stack space. We can reuse the 16
bytes at the top of the stack originally used for the gp and transfer_t.
- Don't bother saving the return address which we never read back.
- Use la to load the address of _exit (purely style).
- Move the "move $a0, $zero" instruction so the assembly can put it in
the delay slot.
- Use "jr" instead of "jalr" because we don't expect _exit to ever
return.

mips: allocate unused stack space for incoming argument area
...
The MIPS ABI requires that 16 bytes of unused stack space is allocated by
the caller when calling functions. Some comments refer to "shadow space"
which might be talking about this, but since the captured_context code
was added, the assembly has not actually allocated any extra space.
Therefore, allocate an extra 16 bytes between the fcontext_t data and
the saved GP which the initial function will use.
Also fix the address of the returned transfer_t which was incorrect
(although fairly harmless since this data is never read).

mips: perform jump through t9 in ontop_fcontext
...
The MIPS ABI requires all calls to be made "through" t9 (so the called
function can easily get its address).

mips: use v0 as temporary for returned transfer_t
...
For functions which return structures indirectly, the MIPS abi requires
the pointer to the returned structure to be in v0 (so in most cases v0
will contain the value passed to the function in a0).

Fix i386/macho routines to correctly return transfer_t in EAX/EDX
...
The OSX 32bit ABI differs from the System V ABI in that 8 byte structs
are returned in registers EAX/EDX instead of passing the address of the
struct on the stack. See: https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/LowLevelABI/130-IA-32_Function_Calling_Conventions/IA32.html
The current implementation for this platform crashes when compiled for
32bit OSX (e.g. when running a 32bit iOS simulator) due to not
satisfying the ABI.
