	(init_legacy_regcache_descr): Pass a pre-allocated regcache_descr
	in as a parameter
	(init_regcache_descr): Initialize register_type.  Pass the descr
	to init_legacy_regcache_descr.  Use register_type instead of
	REGISTER_VIRTUAL_TYPE.
	(register_type): New function.
	(regcache_dump): Replace REGISTER_VIRTUAL_TYPE with register_type.

/* The type of a register. This function is slightly more efficient
then its gdbarch vector counterpart since it returns a precomputed
value stored in a table.
NOTE: cagney/2002-08-17: The original macro was called
REGISTER_VIRTUAL_TYPE. This was because the register could have
different raw and cooked (nee virtual) representations. The
CONVERTABLE methods being used to convert between the two
representations. Current code does not do this. Instead, the
first [0..NUM_REGS) registers are 1:1 raw:cooked, and the type
exactly describes the register's representation. Consequently, the
``virtual'' has been dropped.
FIXME: cagney/2002-08-17: A number of architectures, including the
MIPS, are currently broken in this regard. */
