[Dotgnu-libjit] Support for OSX ABI

[Maarten Hoeben]

I'm trying to get libjit to work under OSX 1.5, x86. I already patched  
tools/gen-apply-macosx.h so that JIT_APPLY_NUM_WORD_REGS and  
JIT_APPLY_NUM_FLOAT_REGS are set to 0. OSX uses the System V ABI,  
where all parameters are passed on the stack. I'm now trying to align  
the stack to a 16 byte alignment, since the x86 environment uses a  
stack that - at the point of function calls - is 16 byte aligned. I  
have been looking for definitions that achieve this, but did not find  
anything. Any thoughts on where to look, or how to get libjit working  
under OSX?
