sim: profile: disconnect from watchpoint core 

The profile code was using STATE_WATCHPOINTS to get access to the PC, but
we already have a standard method for getting the pc, so switch to that.

This assumes that sizeof_pc is the same size as sim_cia, but we already
assume this in places by way of sim_pc_{get,set}, and this is how it's
documented in the sim-base.h API.

2015-03-24 Mike Frysinger <vapier@gentoo.org>
* sim-profile.c (profile_pc_event): Get pc via sim_pc_get. Delete
usage of STATE_WATCHPOINTS.
(profile_pc_init): Delete STATE_WATCHPOINTS (sd)->pc check. Change
STATE_WATCHPOINTS (sd)->sizeof_pc to sizeof (sim_cia).
2015-03-24 Mike Frysinger <vapier@gentoo.org>
* tconfig.h: Note SIM_HAVE_PROFILE is deprecated.
