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.

(only if the full --generate-debug-info is enabled for now).

Add mini-debug-info generation mode for JIT.
This excludes everything that is not needed for backtraces and
compresses the resulting ELF file (wrapped in another ELF file).
This approximately halves the size of the debug data for JIT.
The vast majority of the data is the overhead of ELF header.
We could amortize this by storing more methods per ELF file.
It also adds NOBITS .text section to all debug ELF files,
as that seems necessary for gdb to find the symbols.
On the other hand, it removes .rodata from debug ELF files.
Test: Manually tested that gdb can use this data to unwind.

Refactor linker files from compiler/ to dex2oat/.
This shifts some code from the libart-compiler.so to dex2oat
and reduces memory needed for JIT. We also avoid loading the
libart-dexlayout.so for JIT but the memory savings are
minimal (one shared clean page, two shared dirty pages and
some per-app kernel mmap data) as the code has never been
needed in memory by JIT.
aosp_angler-userdebug file sizes (stripped):
lib64/libart-compiler.so: 2989112 -> 2671888 (-310KiB)
lib/libart-compiler.so: 2160816 -> 1939276 (-216KiB)

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.

Move Assemblers to the Arena.
And clean up some APIs to return std::unique_ptr<> instead
of raw pointers that don't communicate ownership.

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.
