m68k_register_virtual_type

[Andreas Schwab <schwab@suse.de>]

[ Seems like this mail didn't come through although I'm sure it left my
notebook. ]

The m68k sr, fpcontrol and fpstatus registers don't contain addresses, so
they should be treated like any other integer register.  Committed.

	* m68k-tdep.c (m68k_register_virtual_type): Return int for SR, FPC
	and FPS registers.
