Subject: * sysdeps/mips/memcpy.S: Map t0-3 to a4-7 on new abis. *
 sysdeps/mips/memset.S: Likewise. * sysdeps/mips/sys/regdef.h: Alias a4-7 or
 t0-3 to $8-11 depending on the ABI.

	* sysdeps/mips/memcpy.S: Map t0-3 to a4-7 on new abis.
	* sysdeps/mips/memset.S: Likewise.
	* sysdeps/mips/sys/regdef.h: Alias a4-7 or t0-3 to $8-11
	depending on the ABI.
