[v2,3/4] reggroups: Create reggroup_gdbarch_new for dynamic reggroups
Commit Message
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.

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