Allow targets which produce setcc results in non-MVT::i1 registers to describe
...
what the contents of the top bits of these registers are, in the common cases
of targets that sign and zero extend the results.

Change LowerCallTo to take a boolean isVarArg argument. This is needed
...
by the PowerPC backend, and probably others in the future.

Move all data members to the end of the class.
...
Add a hook to find out how the target handles shift amounts that are out of
range. Either they are undefined (the default), they mask the shift amount
to the size of the register (X86, Alpha, etc), or they extend the shift (PPC).
This defaults to undefined, which is conservatively correct.

Revamp supported ops. Instead of just being supported or not, we now keep
...
track of how to deal with it, and provide the target with a hook that they
can use to legalize arbitrary operations in arbitrary ways.
