Reviewed by Tadeu Zagallo.

Currently, we always follow a LLInt comparison instructions with an `and with 1` mask.
This is completely unnecessary because the LLInt comparison instructions already always
produce a 1 or a 0.  Hence, the `and with 1` mask is effectively a no-op.  This patch
removes this unnecessary masking.
