MPIR 64-bit FractServ test

doc: bench mpir64.frs
res: 640x480
q: 4096
aa: 1x
PCs: CHRISK, ENG-WZENGERLE64

32-bit production code:
ET: 274.974
CHRISK: 83
ENG-WZ: 397

64-bit MPIR:
ET: 246.165 s.
CHRISK: 74
ENG-WZ: 406


A 10% improvement, not too impressive but better than nothing.
Hypothesis: maybe zoom isn't deep enough for MPIR to show much improvement. Try using z = 1E100.
