target-i386: Compute all flag data inside %cl != 0 test.
The (x << (cl - 1)) quantity is only used if CL != 0. Move the
computation of that quantity nearer its use.
This avoids the creation of undefined TCG operations when the
constant propagation optimization proves that CL == 0, and thus
CL-1 is outside the range [0-wordsize).
