Rewrite uses of VLOG_IF and LOG_IF.

VLOG_IF's evaluation order is ambiguous - does it mean
`if (cond) VLOG(lvl)` or `if (VLOG_IS_ON(lvl) && cond) LOG(INFO)`?
In particular, the way it works now is inconsistent with the way the
rest of the LOG macros evaluate their arguments.
Fixing this would be hard, and the macro's behavior would still surprise
some people. Replacing it with an if statement is simple, clear, and unambiguous.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.
