This patch implements the set boolean condition instructions introduced in POWER10.

The set boolean condition instructions (`set[n]bc[r]`) are used during these 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

Depends on D86252 <https://reviews.llvm.org/D86252>.
