* tree.h (VAR_DECL_IS_VIRTUAL_OPERAND): New.
(init_function_for_compilation): Remove.
* tree-dfa.c (find_vars_r): Take struct function argument.
(find_referenced_vars_in): Adjust.
* tree-ssa-operands.c (clobber_stats): Remove.
(create_vop_var): Take struct function argument. Mark
virtual operand with VAR_DECL_IS_VIRTUAL_OPERAND.
(init_ssa_operands): Take struct function argument.
(fini_ssa_operands): Do not dump dead stats.
* tree-ssa-operands.h (init_ssa_operands): Take struct function
argument.
* cgraphunit.c (init_lowered_empty_function): Adjust.
* lto-streamer-in.c (input_cfg): Likewise.
* tree-inline.c (initialize_cfun): Likewise.
* tree-into-ssa.c (rewrite_into_ssa): Likewise.
* omp-low.c (expand_omp_taskreg): Likewise. Avoid switching
cfun.
* gimple.c (is_gimple_reg): Optimize the SSA_NAME case,
virtual operands are not registers.
