7b5987d56e 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.

5ebc3dbc1c Change LowerCallTo to take a boolean isVarArg argument. This is needed
by the PowerPC backend, and probably others in the future.

6147a7aa17 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.

7e5ee40979 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.
