Subject: Breakpad Dumper: Move CFI register names to DwarfCFIToModule class.

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.
