[PATCH] testsuite, JIT, Darwin: Adjust asm tests for Mach-O.

[Iain Sandoe <iain@sandoe.co.uk>]

Hi,

This provides adjusted assembler fragments that are suitable
for x86_64 Mach-O.

** as an aside, I wonder if it would be possible to configure some
   conditional on __ELF__, __MACH__, and CPU arch to pull in some
   object-cpu.inc so that we can generalize this for all hosts.

this version tested on x86_64-darwin, x86_64-linux,
OK for master?
thanks
Iain
