gdbarch: add addressable_memory_unit_size method
Add a new gdbarch method to get the length of an addressable memory unit
for a given architecture. The default implementation returns 1.
gdb/ChangeLog:
* arch-utils.h (default_addressable_memory_unit_size): New.
* arch-utils.c (default_addressable_memory_unit_size): New.
* gdbarch.sh (addressable_memory_unit_size): New.
* gdbarch.h: Re-generate.
* gdbarch.c: Re-generate.
