Add unwind annotations for freebsd/x86 getcontext.S.
...
Rearrange the code to put the slow branch out of main body,
and pinch the fixed amount of stack space to be able to annotate
the code.

During the stack unwinding process, the return address points to
...
the instruction after the call for a normal frame. libunwind uses
IP-1 to lookup unwind information. However, this is not necessary for
interrupted frames such as signal frames (or interrupt frames) in
the kernel context.
This patch handles both cases correctly.

Implement getcontext for x86
...
Greetings,
Attached patch implements getcontext for x86.
Motivation is the same as:
http://lists.nongnu.org/archive/html/libunwind-devel/2008-06/msg00009.html
This also fixes check-name-space on x86.
Tested on Linux/86 with no new failures.
Thanks,
