* basic-block.h (REG_BASIC_BLOCK): Use VEC instead of VARRAY.

	* flow.c (reg_n_info): Change the type to
	VEC(reg_info_p,heap) *.
	* regclass.c (allocate_reg_info, free_reg_info): Use VEC
	instead of VARRAY.
	* regs.h (reg_info_p): New.
	(REG_N_REFS, REG_FREQ, REG_N_SETS, REG_N_DEATHS,
	REG_N_CALLS_CROSSED, REG_N_THROWING_CALLS_CROSSED,
	REG_LIVE_LENGTH, REGNO_FIRST_UID, REGNO_LAST_UID): Use VEC
	instead of VARRAY.
