Refactor jit debugger interface and its ELF creation.
Make it possible to store more then one method per entry,
and ref-count the number of live methods per entry.

Add debug info for link-time generated thunks.
Add debug info for method call thunks (currently unused) and
Baker read barrier thunks. Refactor debug info generation
for trampolines and record their sizes; change their names
to start with upper-case letters, so that they can be easily
generated as `#fn_name`.
This improved debug info must be generated by `dex2oat -g`,
the debug info generated by `oatdump --symbolize` remains
the same as before, except for the renamed trampolines and
an adjustment for "code delta", i.e. the Thumb mode bit.
Cortex-A53 erratum 843419 workaround thunks are not covered
by this CL.
Test: Manual; run-test --gdb -Xcompiler-option -g 160, pull
symbols for gdbclient, break in the introspection
entrypoint, check that gdb knows the new symbols
(and disassembles them) and `backtrace` works when
setting $pc to an address in the thunk.

Add trampoline symbols to native debug info.
The debugger needs them to unwind through the trampolines and to
understand what is happening in the call stack.

Refactor MethodDebugInfo (input of DWARF writer).
Do not pass CompiledMethod pointer through since it is only available
during AOT compile but not during JIT compile or at runtime. Creating
mock CompiledMethod just pass data is proving increasingly tricky, so
copy the fields that we need to MethodDebugInfo instead.

Mark DWARF lines in non-debuggable methods as "not a statement".
This is a hint to the debugger that breakpoints and stepping
might not function as intended (since we have limited information).

Split elf_writer_debug.cc to several files.
Refactoring only. The file has grown significantly over time,
and it is time to split it so it can be better managed.

Move code related to debug info generation to its own directory.
debug/dwarf/ contains helper classes which hide the details
of the DWARF file format. It acts as independent DWARF library.
debug/ contains ART-specific code which generates ELF debug
sections (which includes non-DWARF sections like .symtab).
