* gimple-fold.c (get_range_strlen_tree): Record if the computed
length is optimistic. If it is, then arrange to compute the
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.
