Richard Henderson 2623ca6ac1 tcg/i386: Simplify immediate 8-bit logical vector shifts
The x86 isa does not have this operation, so we need an expansion.
Use the same algorithm that we use for expanding this vector
operation with integers: perform the shift with a wider type
and then mask the bits that must be zero.

This reduces the instruction count from 5 to 2.
