New function mps_root_create_reg_masked applies a mask and pattern test to all words in registers and on the stack when scanning them. this supports tagged references in these locations.
...
Consistently use the type "Word *" for pointers into the stack or into saved registers.
Remove TraceScanAreaTagged.

Switched mac os x threading to use thix.c and pthreadext.c.
...
Also switched to using platform specific Mutator Context code
so that we can read out the registers for instruction emulation
and stack scanning.
Builds on 64-bit but doesn't work because sem_init is unimplemented on
Mac OS X.
Not finished on 32-bit.
