Add "maint check xml-descriptions" to test builtin xml target descriptions
Now, GDB is able to dynamically create i386-linux target descriptions
from features, instead of using pre-generated target descriptions. These
pre-generated target descriptions are no longer used by GDB (note that
they are still used by GDBserver).
This patch add a new maint command "maint check xml-descriptions" to test
dynamically generated tdesc are identical to these generated from xml files.
