fix dwz.exp on 32-bit targets
This fixes dwz.exp on 32-bit targets. It does so by introducing a new
"default" setting for the address size in the DWARF assembler.
Built and regtested on x86-64 Fedora 18.
I also ran the gdb.dwarf2 tests on an x86 machine (gcc45).
* lib/dwarf.exp (cu, tu): Handle addr_size of "default". Change
default addr_size.
* lib/gdb.exp (is_64_target): New gdb_caching_proc.
