The z13 vector facility includes some instructions that operate only on the
high f64 in a v2f64, effectively extending the FP register set from 16
to 32 registers. It's still better to use the old instructions if the
operands happen to fit though, since the older instructions have a shorter
encoding.

This adds ABI and CodeGen support for the v2f64 type, which is natively
supported by z13 instructions.
