[v3 patch] add missing export for std::regex_error and fix tests

[Jonathan Wakely <jwakely dot gcc at gmail dot com>]

I found a few tests containing VERIFY assertions that were incorrectly
marked { dg-do compile } so weren't executed, hiding some broken tests
and a missing export. This adds the export and fixes the tests. I
deleted the TR1 test because it won't link due to unimplemented
features so doesn't really test anything.
