epriestley a604548101 Slightly improve base85 performance for 64-bit systems 
Summary:
Ref T13130. I wasn't able make this much better, but it looks like this is about ~20% faster on my system.

This kind of thing is somewhat difficult to micro-optimize because XHProf tends to over-estimate the cost of function calls. In XHProf, this looks much much faster than the old version (~100% faster) but the actual cost of `bin/conduit call --method differential.getrawdiff` hasn't improved that much. Still, it seems consistently faster across multiple runs.

Test Plan:
  - Pulled binary diffs over Conduit with `bin/conduit call --method differential.getrawdiff`.
  - Verified that they are byte-for-byte identical with the pre-change diffs, and look like they're ~20% faster.
  - Profiled the differences and saw a far more dramatic improvement, but I believe XHProf is exaggerating the effect of this change because it tends to overestimate function call cost.
  - Ran unit tests (from D19407), got byte-for-byte identical output under both 32bit and 64bit mode.
