[patch] Skip offsets when reading resolution files

[Rafael Espindola]

Currently lto1 gets confused when reading resolution files that
contains lines like

foo.a@123

in them. The problem is that the expected filename is only foo.a. The
attached patch fixes the problem by remembering and checking the
offset.

	* lto-elf.c (lto_file_init): Add offset argument.
	(lto_elf_file_open): Record the offset.
	* lto.c (lto_resolution_read): Change file_name into a lto_file
argument. Check offsets.
	(lto_file_read): Update call to lto_resolution_read.
	* lto.h (lto_file_struct): Add the offset field.
