e2962af9d3 Implement a cheaper getcontext() 
Since the fast unwinding code path doesn't need the full context,
a faster target dependent getcontext is implemented.

5f38f35d5d 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.

9e98f15e9a 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.
