This patch avoids allocating many copies of identical strings appearing in
debugging information. Without this patch, running dump_syms on Mozilla's
libxul.so (with 173MiB of debugging information) has a peak resident set of
around 450MiB. With this patch, the peak is around 365MiB.

At the moment, the mappings from register numbers appearing in DWARF CFI
and .eh_frame exception handling sections to the appropriate
processor-specific names are in src/common/linux/dump_syms.cc. However, the
numberings are (for the most part) the same on all platforms using DWARF,
so there's no reason those tables shouldn't be shared between the Linux and
Mac symbol dumpers.
This patch moves the tables into a nested class of DwarfCFIToModule, so
they the Mac dumper can use them when it is changed to use
DwarfCFIToModule.

The Linux symbol dumper's classes are reasonably portable, and should be
usable for the Mac dumper as well. Move them to src/common, along with
their unit tests. Update #include directives and Makefile.
