19e81ce51e68d9a1e6a317cd3f3e519757d16dfd target/ppc: Rename TBL to TB on 64-bit
From the earliest PowerPC ISA, TBR (later SPR) 268 has been called TB
and accessed with mftb instruction. The problem is that TB is the name
of the 64-bit register, and 32-bit implementations can only read the
lower half with one instruction, so 268 has also been called TBL and
it does only read TBL on 32-bit.
Change SPR 268 to be called TB on 64-bit implementations.
