Rename ENABLE_EXTRA_COMPILER_CHECKS to ENABLE_EXTRA_COMPILER_WARNINGS.

This matches the current name of the --enable-extra-compiler-warnings
option in autotools.

Fix the documentation of the option to match.

(Note that "compiler" won't necessarily always be GCC or Clang, and
won't necessarily always use -W for warning options, so speaking of them
as "-W checks" isn't future-proof.)
