2015-06-03tcg: add TCG_TARGET_TLB_DISPLACEMENT_BITSPaolo Bonzini
This will be used to size the TLB when more than 8 MMU modes are used by the target. Limitations come from the limited size of the immediate fields (which sometimes, as in the case of Aarch64, extend to instructions that shift the immediate).
