simpleperf: fix dumping arm regs on arm64 devices.
On arm64 devices, the kernel dumps arm64 regs
even for 32-bit processes. So we need to map
from arm64 registers to arm registers.
Bug: http://b/30974693
Test: run simpleperf manually on one app.

simpleperf: fix unwind stack size.
Currently, to work around the bug in N9, simpleperf uses
all dumped user stack for unwinding. However, not all of
the data is valid, which can make unwinding result annoying.
So fix this by using only valid stack data if dyn_size != 0.
Bug: 29574526
Test: run simpleperf_unit_test and use simpleperf manually.

simpleperf: use libbacktrace_offline static library.
Device may not have libbacktrace_offline shared library, so always
using libbacktrace_offline static library.
Use simpleperf namespace to avoid conflicts with ThreadEntry in
libbacktrace.

simpleperf: loosen unwinding arch check for system wide collection.
When doing system wide collection, it is possible that there are
32-bit compat processes running on 64-bit devices. It is not proper
to abort in this situation. So loosen the check to allow it. Also
add corresponding test.

Simpleperf: remove dependency on global current_arch.
When running unit tests on arm64 devices:
[OK] ReportCommandTest.dwarf_callgraph
[OK] record_cmd.dwarf_callchain_sampling.
ERROR: can't unwind data recorded on a different architecture.
It is because ReportCommandtest.dwarf_callgraph opens a perf.data
recorded on x86_64, and changes current_arch. It causes a problem when
the test record_cmd.dwarf_callchain_sampling calls libbacktrace built
on aarch64. Athough it doesn't make the test fail, we should fix this.

Simpleperf: warn if it can't read kernel symbols addresses.
And a little format adjustment.

Simpleperf: support dwarf callgraph in report command.
Use libbacktrace for stack unwinding.
