Power4 should treat mftb as extended mfspr mnemonic
On further reading of ISA manual it appears gas should have been
treating mftb and mftbu as extended mnemonics for mfspr, for ISA 2.03
and later.
opcodes/
* ppc-opc.c (powerpc_opcodes): Make mftb* generate mfspr for
power4 and later.
gas/testsuite/
* gas/ppc/a2.d: Update for mftb change.
* gas/ppc/476.d: Likewise.
