Andrew Turner 91569f1f38 Increase the size and alignment of the setjmp buffer. This will allow for
possible future CPU extentions with larger registers.

jmp_buf's size and alignment are baked into the ABI of third party libraries
and thus are very hard to change later so it is best to waste a small amount
of space now.
