Change the 'isStore' inferrer to look for 'SDNPMayStore'
instead of "ISD::STORE". This allows us to mark target-specific dag
nodes as storing (such as ppc byteswap stores). This allows us to remove
more explicit isStore flags from the .td files.
Finally, add a warning for when a .td file contains an explicit
isStore and tblgen is able to infer it.
