rs6000: Merge the var_shift yes/no alternatives
All instructions that are "var_shift" for some alternative have the shift
amount as operands[2].
This patch introduces an attribute "maybe_var_shift". If that is set to
"yes", the default value of "var_shift" is set based on the operands[2]
value.
With that, we can merge the var_shift yes/no cases everywhere. Do so.
Also change some more "i" to "n".
