These can be generally described as removing redundant condition checks, using logical operators instead of bitwise operators, removal of redundant parenthesis, and consistent use of pragma push and pragma pop. There is very little observable behavior change in this CL.
Changes that required further review are pending in 2489753

#summary Rename Trunc, Round, Floor, Ceil to TruncToInt, RoundToInt, FloorToInt, CeilToInt. Added *ToFloat versions. Repeated for FGenericPlatformMath and all derived classes for all platforms wherever applicable. Corrected comment in Fractional and added Frac() which does HLSL-style fractional (x - floor(x)). Checked for compilation on all projects (with cooking levels wherever applicable). Didn't change Fractional to Frac, this will be done in second commit.
