This patch implements the set boolean condition instructions introduced in
POWER10.
The set boolean condition instructions (set[n]bc[r]) are used during
the following situations:
- sign/zero/any extending i1 to an i32 or i64,
- reg+reg, reg+imm or floating point comparisons being sign/zero extended to i32 or i64,
- spilling CR bits (using the setnbc instruction)

This patch legalizes the v256i1 and v512i1 types that will be used for MMA.
It implements loads and stores of these types.
v256i1 is a pair of VSX registers, so for this type, we load/store the two
underlying registers. v512i1 is used for MMA accumulators. So in addition to
loading and storing the 4 associated VSX registers, we generate instructions to
prime (copy the VSX registers to the accumulator) after loading and unprime
(copy the accumulator back to the VSX registers) before storing.
This patch also adds the UACC register class that is necessary to implement the
loads and stores. This class represents accumulator in their unprimed form and
allow the distinction between primed and unprimed accumulators to avoid invalid
copies of the VSX registers associated with primed accumulators.
