reggroups: Add reggroup_gdbarch_new, reggroup_find for dynamic reggroups
Traditionally reggroups have been created via reggroup_new() during
initialization code and never freed. Now, if we want to initialize
reggroups dynamically (i.e. in target description) we should be able to
free them. Create this function reggroup_gdbarch_new() which will
allocate the reggroup memory onto the passed gdbarch obstack.
Also creating reggroup_find() as a utility to find a gdbarch registered
reggroup object by name.
gdb/ChangeLog:
yyyy-mm-dd Stafford Horne <shorne@gmail.com>

(reggroup_find): New function.
* reggroups.h (reggroup_gdbarch_new): New function.
(reggroup_find): New function.
