Amy Kwan b378d94cb6 [PowerPC] Implement Set Boolean Condition Instructions
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)

; comparisons (cmplwi, cmpldi). This is because alternative code is generated
; when there is a compare (logical or not), followed by a sign or zero extend.
; This codegen will be re-evaluated at a later time on whether or not it should
