[rfc] [00/05] Get rid of current_gdbarch

[Markus Deuling]

Hi,

this is the next series of 5 patches to get rid of current_gdbarch.

Patch 5 introduces a new function to replace the AREG_NUMBER macro. I tested it by building GDB with 
--target=xtensa. I'd appreciate very much if anyone with access to a xtensa machine could test this one.

I tested this patch set with gdb_mbuild.
