Fix parameter passing through makecontext (again).

Use an union to avoid risky binary operations such as shift or cast with
signed ints.

For example on x86_64 arch, address 0x00007f89d445e010 was recomputed as
0xffffffffd445e010, because (uintptr_t)(int)0xd445e010 is 0xffffffffd445e010,
thanks to sign extension.
