cgraph.c (cgraph_function_body_availability): Handle weakref correctly.
* cgraph.c (cgraph_function_body_availability): Handle weakref
correctly.
* passes.def: Remove pass_fixup_cfg.
* ipa-inline.c (ipa_inline): When not optimizing, do not inline;
track when we need to remove functions.
(gate_ipa_inline): Execute inlining always; add comment why.
(pass_data_ipa_inline): Remove TODO_remove_functions.
* ipa-inline-analysis.c (inline_generate_summary): When not optimizing
do not produce summaries.
* symtab.c (change_decl_assembler_name): Handle renaming of weakrefs.
(symtab_nonoverwritable_alias): Assert we are not called on weakref.
* varpool.c (cgraph_variable_initializer_availability): Fix weakrefs,
constant pool and vtable.
