fef5de6c45 Move ret_addr_column and signal_frame from dwarf_reg_state to 
dwarf_reg_cache_entry, leaving in dwarf_reg_state only what
apply_reg_state needs.

5d0f376b08 Invert tdep_init() flag logic 
Invert the flag that signals that tdep_init() was called, to move the
symbol from data to BSS.

d93d96ad83 Fix compilation on IA64 
- Add tdep macro for {dwarf,ia64}_find_unwind_table so that ia64
   doesn't try to use dwarf code.
 - Fix extraneous #if.
 - Fix mistyped filename in Makefile.am.
 - Link ia64-specific tests with correct libraries.

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.

3842dac733 Add initial ARM and MIPS support. To support this, also enable the 
reading of .debug_frame sections (used in lieu of .eh_frame sections
when they're not available).
