Adding libdw DWARF post unwind support, which is part
of elfutils-devel/libdw-dev package from version 0.158.
Also includes the test suite for dwarf unwinding, by adding the
arch specific test code and the perf_regs_load function.

Hi,
Here are some notes about the performance improvement and the test usage.
Jiri, do you need these notes in the one of commit description?
1. Using libdw vs libunwind on ARMv7

Hi,
Here are some notes about the performance improvement and the test usage.
Jiri, do you need these notes in the one of commit description?
1. Using libdw vs libunwind on ARMv7
The performance gain is (more than) significant: >800%.
I did not profile perf itself ;-p just did a timing
