[regex] BZ #522 Enable UTF-8 and ASCII optimizations outside glibc, take 2

This patch is not correct.

First, you introduce additional work in the glibc path.  There is no
need to check for UTF8, we know it is UTF-8.

Second, the dfa->mb_cur_max == 6 test does not necessarily apply to all
platforms.  It should be removed outside of glibc.

In fact, the glibc code should stay as is.

You also introduced an inconsistency: the regex_internal code uses
isascii() while you explicitly test for <= 127.

I made these changes and applied the patch.
