[PATCH] Some small optimizations

Which previous patch? From Matt?

Matt,

The ext/* patches were applied to 5.2, I'll commit the Zend/ ones once
we have an agreement on the previous patch.

Hi,

Here are patches to use Brian Shire's optimizations (applied by Ilia
to 5.2 the other day) in a couple more places, and for HEAD. In
Unicode mode, concat_function() is up to 20%+ faster! (Probably
because zend_make_unicode_zval() calls TSRMLS_FETCH(); so not so much
with non-ZTS I guess.)

Also removed a few strlen() calls that I noticed when looking at
is_numeric_string's usage awhile ago. :-)
