re PR tree-optimization/63989 (tree-ssa-strlen.c doesn't handle constant pointer plus and array refs if constant offset is smaller than known constant string length)

	PR tree-optimization/63989
	* params.def (PARAM_MAX_TRACKED_STRLENS): Increment default
	from 1000 to 10000.
	* tree-ssa-strlen.c (get_strinfo): Moved earlier.
	(get_stridx): If we don't have a record for certain SSA_NAME,
	but it is POINTER_PLUS_EXPR of some SSA_NAME we do with
	constant offset, call get_stridx_plus_constant.
	(get_stridx_plus_constant): New function.
	(zero_length_string): Don't use get_stridx here.

	* dse.c (struct insn_info): Mention frame_read set also
	before reload for tail calls on some targets.
	(scan_insn): Revert 2014-12-22 change.  Set frame_read

	instead of add_non_frame_wild_read for non-const/memset
	tail calls after reload.
