[rfc][3/13] Eliminate read_register: read_register in mep-tdep.c current_ routines

[Ulrich Weigand]

Hello,

another place in a tdep file where global register state is accessed
in a way that isn't easily eliminable: current_me_module and 
current_options in mep-tdep.c.


To be able to continue elimination of read_register, this patch simply
inlines the definition and reads from current_regcache.  This should
obviously have no change in behaviour.


Bye,
Ulrich


ChangeLog:

	* mep-tdep.c (current_me_module): Read from current regcache
	instead of calling read_register.
	(current_options): Likewise.
