  [Sparc] Remove duplicate ALU and SETHI instructions (NFCI) (#66851)

There are no 64-bit variants of these ALU / SETHI instructions in V9.
Remove these instruction definitions and add patterns to match DAG nodes
to the generic instructions defined in SparcInstrInfo.td.

This is not strictly NFC because of the changes in
`2011-01-11-FrameAddr.ll` test. The reason is that Sparc delay slot
filler pass handled ADDrr but not ADDXrr, which are now the same
instruction.
