From 6c2cf8b1fbcf70fd9db6fe44032c1ceaa2299760 Mon Sep 17 00:00:00 2001

Subject: Add a new MachineJumpTableInfo entry type, EK_GPRel64BlockAddress,
 which is needed to emit a 64-bit gp-relative relocation entry. Make changes
 necessary for emitting jump tables which have entries with directive
 .gpdword. This patch does not implement the parts needed for direct object
 emission or JIT.
