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) Differential Revision: https://reviews.llvm.org/D87705
