Log message:
	2000-07-12  Michael Snyder  <msnyder@cleaver.cygnus.com>
	
	* regcache.c (registers_changed, registers_fetched): Use
	ARCH_NUM_REGS directly, eliminating an unnecessary variable.
	
	This change adds pseudo-register capability to GDB.
	Pseudo-registers are handled like registers, but they
	don't come from or live on the target.  They may be
	aliases for an existing register, or they may be computed.
	* defs.h (NUM_PSEUDO_REGISTERS): Define default of zero.
	(ARCH_FETCH_PSEUDO_REGISTERS): Define default of no-op.
	(ARCH_STORE_PSEUDO_REGISTERS): Define default of no-op.
	# regcache.c (registers_changed): Mark pseudo-registers
	invalid, as well as real registers.
	(registers_fetched): Do not mark pseudo-registers as fetched
	at the same time as other (real) registers.
	(read_register_bytes): Fetch pseudo-registers (if any) from
	the target architecture module instead of from the target.
	(read_register_gen): Ditto.
	(read_register): Ditto.
	(write_register_bytes): Store pseudo-registers (if any) to
	the target architecture module instead of to the target.
	(write_register_gen): Ditto.
	(write_register): Ditto.
	(build_regcache): Allocate enough register_valid space for
	pseudo-registers as well as normal (real) ones.
