Drop a call frame in tdep_trace and avoid a call to unw_step.
...
Dropping the extra frame for unw_backtrace itself using unw_step is
approximately 15% slower than skipping the frame in tdep_trace. So
drop the frame in the latter, and make the function a private
implementation detail for libunwind, not an exported interface.
Also moves unw_getcontext call back into unw_backtrace to avoid an
extra call frame in case slow_backtrace does not get inlined into
unw_backtrace.

Fast back-trace for x86_64 for only collecting the call stack.
...
Adds new function to perform a pure stack walk without unwinding,
functionally similar to backtrace() but accelerated by an address
attribute cache the caller maintains across calls.

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,

Set UNW_TDEP_SP on x86 to ESP
...
This is similar to what has been done on other archs and resolves an out of
bounds array access elsewhere.

[dwarf] The sword() function in Gexpr.c doesn't do what's intended.
...
Yes, it casts to signed, but then converts right back to
unsigned via the return type. Fixed thus.
