- (vt_initialize): Change return type to bool. Move most of pool etc.
- initialization to the beginning of the function from end. Pass
- CSELIB_RECORD_MEMORY | CSELIB_PRESERVE_CONSTANTS to cselib_init.
- If !frame_pointer_needed, call vt_stack_adjustment before mos
- vector is filled, call vt_init_cfa_base if argp/framep has been
- eliminated to sp. If frame_pointer_needed and argp/framep has
- been eliminated to hard frame pointer, set
- hard_frame_pointer_adjustment and call vt_init_cfa_base after
- encountering fp setter in the prologue. For MO_ADJUST, call
- log_op_type before pusing the op into mos vector, not afterwards.
- Call adjust_insn before cselib_process_insn/add_with_sets,
- call cancel_changes (0) afterwards.
- (variable_tracking_main_1): Adjust for vt_initialize calling
- vt_stack_adjustments and returning whether it succeeded or not.
