Make CHECK not print messages in official builds

Make CHECK not print messages in official builds

This cuts down on the number of strings in the executable, as well as
executable code to print them.

On Linux, this saves 208kb on a stripped official build
(chrome executable file went from 64569072 bytes -> 64782064 bytes)

On OS X, this saves 209kb on an official build (Google Chrome Framework went from 51483872 bytes -> 51274984 bytes)

On Windows, this saves 139kb on an official build (chrome.dll went from 28619264 bytes -> 28477440 bytes)

Fix test failure in logging_unittest.cc in official builds.

Add new executable check_example for easy testing of changes to the
CHECK macros.

The commit queue went berserk retrying too often for a
seemingly flaky test. Builder is mac_rel, revision is 112568, job name
was 8734021-1 (previous was lost) (previous was lost) (retry) (previous was
lost).

Try job failure for 8734021-1 (retry) on linux_rel for step "compile" (clobber
build).
It's a second try, previously, step "compile" failed.
