* SConstruct: Use only code files for TAGS.

* SConstruct[GO_FAST_BUTTON]: implement tips from Andreas Roach.
This brings SCons run-time on up-to-date tree down from 48s with
only checksums, to 34s without 2day checksums, to 14s (make needs
4 seconds).
(subdirs)[GO_FAST_BUTTON]: Try to read all subdirs only when
necessary.
