Adjust the vbit tester to deal with shift operations that require
an immediate constant as the shift amount. This is needed for
powerpc Iop_ShlD64 etc. What it basically means that we do not
iterate over the bits in the 2nd operand because there are no
V-bits to set. An immediate constant is always completely defined.
Fixes bugzilla #305948.
