Add 'isCodeGenOnly' bit to Instruction .td records.
 - Used to mark fake instructions which don't correspond to an actual machine

now that JumpTableDirective can differentate picness itself, MIPS TAI

split "JumpTableDirective" (an existing hack) into a PIC and nonPIC
version.  This allows TAI implementations to specify the directive to use
based on the mode being codegen'd for.

The real fix for this is to remove JumpTableDirective, but I don't feel
like diving into the jumptable snarl just now.
