Assorted DW_FORM_implicit_const fixes
The problem is I think that write_abbrev is always called before write_info,
and the remapping of the DW_AT_decl_file/DW_AT_call_file DW_FORM_implicit_const
is done only in write_die which is called either recursively or from
write_info/write_types. Which means the DW_FORM_implicit_const value encoded
in the abbrev was never updated.
Other fixes include hashing the DW_FORM_implicit_const value in checksum_die
and more importantly comparing the values in die_eq_1.

* dwz.c (checksum_die): For DW_FORM_implicit_const hash t->values[i].
(die_eq_1): For DW_FORM_implicit_const compare t?->values[?].
(build_abbrevs_for_die): For DW_FORM_implicit_const on DW_AT_*_file
call line_htab_lookup too and store the result into t->values[j].
Otherwise, handle even file ids larger than 32-bit.
(write_die): For DW_FORM_implicit_const on DW_AT_*_file just j++
and continue, don't call line_htab_lookup nor adjust anything.
Simplify.
(alt_clear_dups): Fix function comment.
