Ignore empty maps when emitting DWARF variable locations.

This is rewrite of https://android-review.googlesource.com/#/c/202115

The aim in both cases is to avoid gaps in generated locations.
(which helps to keep the size of the generated DWARF down).

However, the previous CL was a bit too eager with extending of
variable scope and reporting locations. We might have reported
variable in scope when in fact, it was not.

This CL implements simpler solution by just filtering stackmaps
without dex register maps at first opportunity. This should
ensure that locations for breakpoint locations are completely
accurate as originally intended.

Symbolize native debug information for AOTed methods in boot.oat.

The oatdump symbolizer will produce all DWARF information now,
not just the symtab. This allows us to recover almost all native
debug information after the fact, even for non-debuggable oat files.

The main drawback is that non-debuggable oat files do not have
enough stackmaps to provide reasonable line stepping experience.
We might also be missing inlined methods from backtraces.

trouble when generating native line number mapping since the
