The Wide_Wide_Hash version of Ada.Strings.Hash was instantiated as a
library unit. Now all versions are instantiated in wrapper functions.
Minor inconsistency, spotted while cleaning up code for categorization
pragmas on instance units.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* libgnat/a-stzhas.adb (Wide_Wide_Hash): Instantiate inside a
wrapper function.
* libgnat/a-stzhas.ads (Wide_Wide_Hash): Likewise; remove wrong
comment, because this is indeed a RM unit, as described in Ada
RM A.4.8 (1/3).
