target/ppc: introduce get_fpr() and set_fpr() helpers for FP register access

These helpers allow us to move FP register values to/from the specified TCGv_i64
argument in the VSR helpers to be introduced shortly.

To prevent FP helpers accessing the cpu_fpr array directly, add extra TCG
temporaries as required.
