clang+amd4: fix stack alignment for continuations.
* unwind.h (UW_FRAME_ALIGN): Define on __amd64__, if compiled
by __clang__. This is because MMX instructions are used for
manipulating the stack which require 16 byte alignment.
This was discovered as a bus error crash on OpenBSD in the
tests/012/cont.tl test case, acessing otherwise perfectly
valid memory. The faulting address was only 8 byte aligned,
not 16.
