In Mac dump_syms, allow reading debug data out of both the Mach-O file and the dSYM.
This adds a new |-g <dSYM path>| flag to dump_syms, to specify the dSYM path for
the target Mach-O argument. The UUIDs and architectures of the two paths must
match in order to dump symbols for this "split module."
This reason for this is that for x86_64 binaries on OS X, the CFI data is stored
in the __TEXT,__eh_frame segment of the Mach-O file, and the data is not copied
into the dSYM by dsymutil. Therefore, just dumping the dSYM doesn't yield CFI
data for x86_64 files, and both the dSYM and the Mach-O file must be dumped in
order to produce a complete Breakpad symbol file. For i386 binaries, the CFI data
is stored in the __DWARF,__debug_frame segment, which is part of the dSYM, so
this isn't necessary.
