Andreas Kling d5eed2632f AsmInt: Add branch_zero32/branch_nonzero32 to the asmint DSL ...

These test only the low 32 bits of a register, replacing the previous
pattern of `and reg, 0xFFFFFFFF` followed by `branch_zero` or
`branch_nonzero`.

On aarch64 the old pattern emitted `mov w1, w1; cbnz x1` (2 insns),
now it's just `cbnz w1` (1 insn). Used in JumpIf, JumpTrue, JumpFalse,
and Not for the int32 truthiness fast path.
