vec: use inexact growth where possible.
gcc/ChangeLog:
* cfgrtl.c (rtl_create_basic_block): Use default value for
growth vector function.
* gimple.c (gimple_set_bb): Likewise.
* symbol-summary.h: Likewise.
* tree-cfg.c (init_empty_tree_cfg_for_function): Likewise.
(build_gimple_cfg): Likewise.
(create_bb): Likewise.
(move_block_to_fn): Likewise.
