ae5c1f2adf Performance optimisations for fast trace. 
Insert static branch prediction predicates in useful places and avoid
unnecessary code in the hottest paths. Bypass unnecessary indirect
calls, in particular to access_mem(), when known to be safe.

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

fd21d07fe4 Create a generic and local variant of the extbl parser. 
In order to have the DWARF_* macros working properly a generic and a local
variant of the ex_tables.c have been created.

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.

0f9937485e ARM: Return the dwarf.cfa in case the user requests SP/R13. 
Usually we don't have a valid location for the SP but we keep calculating

f053677198 Remove the ARM_EXIDX_TABLE_MALLOC code path.

cf8d5e41af Have the ARM extbtl-parser operate on the DWARF model directly. 
This eliminates the arm_stackframe and therefore the need to synchronize the
two models. It also clears the way for unwinding call stacks with mixed
DWARF- and extbl-frames.

b115ab645a Ignore separate debug files which contain a .gnu_debuglink section. 
Current implementation fails to find separate debug symbols when
.gnu_debuglink is set to the same name of the target ELF basename
(e.g. "libc.so.6" for /lib/libc.so.6). This patch fixes this by ignoring
separate debug files that contain a .gnu_debuglink section.

It also fixes a small typo in a related Debug() line.

a9dce3c06e 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.

5715d912f4 Make setjmp/longjmp work at least on FreeBSD/amd64. 
FreeBSD-supplied setjmp() saves incremented stack pointer into jmpbuf.

I have no idea whether siglongjmp ever worked on amd64, since
UNW_NUM_EH_REGS == 2 and abort at siglongjmp.c:81 is firing.

f8a15e9679 Fix a couple of test breakages on x86_64 
setcontext() now restores the signal mask. Also remove a check
in the test that doesn't seem to be valid.
