ppc32/64: fix back chain pointer
...
The ABI states that sp[0] should point to the previous stack frame, or be
zero if there is no previous stack frame. makecontext previously set this
slot to point to the __start_context function, rather than to a valid
stack frame.

Reorder registers in other x86_64 assembler files
...
This fixes the previous commit which changed the register order in
swapcontext only, which caused setcontext to subtly corrupt the stack.

fix x86_64 register order for swapcontext
...
rbp and rsi were reversed causing argument passing to fail since
rsi is used to pass 2nd argument.
