[PATCH] [x86_64] Don't truncate PC-relative relocations in ELF EH frames to 32 bits

[Lang Hames]

We can't turn this on my default (as in this patch), but based on discussion with Nick Kledzik I think it should probably be turned on for the large code model (which I believe FTL uses).

Do you know how this is being handled on Darwin? From a glance at InitMachOMCObjectFileInfo I'd have expected you to be seeing the same thing there?
