Rather than crashing in match_results::format() when a reference to a
marked subexpression is out of range, format the subexpression as empty
(i.e., replace it with an empty string). Note that
match_results::operator[]() has a range-check and returns a null match
in this case, so this just re-uses that logic.

Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.
This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.

After months of work there are only 4 tests still failing in C++03.
This patch fixes those tests.
All of the libc++ builders should be green.

We already have a definition for the Czech locale name in
platform_support.h. Use this one instead.
While there, respect the common format of the tests. For most other
tests it's the case that test_iterators.h is placed right underneath the
other #includes (without an empty line). platform_support.h is included
after an empty line.
