	conservative length as well.

	* gimple-fold.h (get_range_strlen): Update prototype.
	* builtins.c (check_access): Update call to get_range_strlen to use
	c_strlen_data pointer.   Change various variable accesses to instead
	pull data from the c_strlen_data structure.
	(check_strncat_sizes, expand_builtin_strncat): Likewise.
	* calls.c (maybe_warn_nonstring_arg): Likewise.
	* tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise.  Reset
	minimum length if maximum lengh is unknown.
	* gimple-ssa-sprintf.c (get_string_length): Likewise.  Drop code
	that used c_strlen, it's no longer needed.  Restructure slightly.
	(format_string): Set unlikely range appropriately.
	* gimple-fold.c (get_range_strlen): Update comments.  Fix minor
	formatting issues.
	(get_range_strlen):  Accept c_strlen_data pointer for external
	call sites as well.  Pass through to call to internal get_range_strlen.
	Adjust minlen, maxlen and maxbound as needed.
	(get_maxval_strlen): Update comments.
	(gimple_fold_builtin_strlen):  Update call to get_range_strlen
	to use c_strlen_data pointer.  Change variable accesses to instead
	use c_strlen_data data members.

	* gimple-fold.c (get_range_strlen): Update prototype.
	(get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
	local variables.  Use pdata to return information to caller.
	Update calls to get_range_strlen.  Update pdata->maxbound.
	(get_range_strlen -- static version): Similarly.
	(get_range_strlen -- extern version): Update for internal
	get_range_strlen API change.  Convert to external data format.
	(get_maxval_strlen): Similarly.

	* coverage.c (get_coverage_counts): Use current_function_decl.
	* profile.c (read_thunk_profile): New function.
	(branch_prob): Add THUNK parameter.
	* tree-profile.c (tree_profiling): Handle thunks.
	* value-prof.c (init_node_map): Handle thunks.
	* value-prof.h (branch_prob): Upate prototype.
	(read_thunk_profile): Declare.
