This is a reland of c195e902
with a higher token limit in check_op.cc to accommodate release component
dcheck_always_on=true builds on Linux (see crbug.com/1069971).

It also addresses some post-commit comments on the original CL.

Original change's description:
> [base] Move the CHECK and CHECK_op macros to more light-weight headers
>
> This provides cheaper (in terms of compile time) alternatives for code
> that just wants to do a few simple CHECKs without pulling in the full
> weight of logging.h. On Linux, the preprocessed size of check.h and
> check_op.h are 2% and 62% of logging.h, respectively.
>
> Splitting the CHECK and CHECK_op macros out to separate files also
> reduces the complexity of logging.h which has become very complicated.
>
> As a bonus, the new implementation is leaner, causing a 3% local
> compile-time reduction for the chrome target on Linux even though no
> includes have been changed yet.
