Support for DW_OP_addrx and DW_FORM_addrx tags

Browse Source 
DW_OP_addrx is the new name of DW_OP_GNU_addr_index, and DW_FORM_addrx
is the name of DW_FORM_addr_index in the Dwarf 5 standard. This is a small
step towards supporting Dwarf 5 in gdb.

Note: I could not find any tests specifically for *_GNU_addr_index, and
I did not add any new tests, please advise.
