lto-cgraph.c: Include gcov-io.h
* lto-cgraph.c: Include gcov-io.h (output_profile_summary): New function. (output_cgraph): Use it. (input_profile_summary): New function. (input_cgraph): Use it. * coverage.c (build_ctr_info_value): Use varpool; initalize DECL_ASSEMBLER_NAME. (create_coverage): Likewise. * tree-profile.c (tree_init_ic_make_global_vars): Likewise. (tree_init_edge_profiler): Likewise. * Makefile.in (lto-cgraph.o): Add dependency on gcov-io.h. From-SVN: r154100
