This makes the assembly much more readable.

No difference between disassembled .o file before and after. file: [47d3793287] check-in: [780d096371] user: js, branch: trunk, size: 11223 [annotate] [blame] [check-ins using] [diff]

When using GCC (and thus conforming to the ABI), do not pass the low
half of an __int128 in a register while passing the high of an __int128
on the stack.

For Clang, just handle it as two longs. file: [2253358a2d] check-in: [15eed89995] user: js, branch: trunk, size: 8224 [annotate] [blame] [check-ins using] [diff]

GCC correctly aligns __int128 with 16 bytes on the stack, like specified
in the ABI, while Clang does not.

Unfortunately, this means that GCC and Clang have a different ABI and
thus are incompatible as soon as code uses __int128. file: [1d2004b374] check-in: [c14dfdc8e5] user: js, branch: trunk, size: 7963 [annotate] [blame] [check-ins using] [diff]

Jumping is useful in case of forwarding, so that the return value does
not need to be put back into an OFInvocation and then from an
OFInvocation back into registers. file: [8ed55a5c76] check-in: [d6e5e6beb3] user: js, branch: trunk, size: 6904 [annotate] [blame] [check-ins using] [diff]

This makes it easier to add more complex types. file: [7689390f4e] check-in: [8417c40405] user: js, branch: trunk, size: 6862 [annotate] [blame] [check-ins using] [diff]

So far this is only for x86_64 with the Apple runtime and does not yet
support all types. It also does not yet support passing arguments via
the stack. file: [ed5f594770] check-in: [95797a4d1c] user: js, branch: trunk, size: 4427 [annotate] [blame] [check-ins using]
