Review 2: Readability of binary constants

[jzmaddock]

Several binary literals throughout the codebase are difficult to read. For instance:

UINT64_C(0b10000000000000000000000000000000000000000000000000)

might become:

UINT64_C(1) << 49

This one is low priority, "nice to have" IMO.

[ckormanyos]

C++14 and beyond support so-called digit separators. I usually use a single quote for separation. Groups of 3, 10, etc. digits are easier to read.
