5715d912f4 Make setjmp/longjmp work at least on FreeBSD/amd64. 
FreeBSD-supplied setjmp() saves incremented stack pointer into jmpbuf.

I have no idea whether siglongjmp ever worked on amd64, since
UNW_NUM_EH_REGS == 2 and abort at siglongjmp.c:81 is firing.

f8a15e9679 Fix a couple of test breakages on x86_64
