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".

This uses the rotl* extended mnemonics instead of the rlw*nm and rld*cl
mnemonics, because they are shorter and more importantly they look the
same for 32-bit and 64-bit.

For this create a new mode_attr "hH".
Also change "i" constraints on the shift amount to "n", which better
describes what it really is (GCC takes the integer value of these
operands and does arithmetic on them; symbolic constants will not work
here).
Also merge the "dot" insns with the corresponding splitters. To do
this, don't allow the dot insns for CBE non-microcode mode at all
(it previously would just split it back always).
