269bd5d8f6 cpu: Move the softmmu tlb to CPUNegativeOffsetState 
We have for some time had code within the tcg backends to
handle large positive offsets from env.  This move makes
sure that need not happen.  Indeed, we are able to assert
at build time that simple offsets suffice for all hosts.

a40ec84ee2 tcg: Create struct CPUTLB 
Move all softmmu tlb data into this structure.  Arrange the
members so that we are able to place mask+table together and
at a smaller absolute offset from ENV.
