[PATCHv2 1/5] gdb/ada: Update some predicate functions to return bool
A later commit would like to make use of a pointer to the function
ada_is_string_type, however, this will require the function to return
a bool (so the signature matches).
As the ada_is_string_type is a predicate function, and its return
value is only ever used as either true or false, then this commit
updates the function to return a bool.
As a consequence ada_is_character_type needs to change too.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* ada-lang.c (ada_is_character_type): Change return type to bool.
(ada_is_string_type): Likewise.
* ada-lang.h (ada_is_character_type): Update declaration
(ada_is_string_type): Likewise.
