[libcxx] Fixup a few fumbles in the initial no-exceptions XFAILs list.
The initial buildbot run found a few missing bits in the initial XFAIL list
for the no-exceptions libc++ variant. These discrepancies are as follows:
 Following two tests need XFAILs on the no-exceptions library variant.
My local runs had these two disabled for other reasons (unsupported):
 These three does not need XFAILs, they were failing on my local runs for
(these are failing on my box for the default build as well)
The current patch fixes both the cases above. Additionally, I've run the
following scan to make sure I've covered all the cases:
> grep ' catch \| try \| throw ' -R . | perl -pe 's|(.*?):.*|\1|' | sort | \
uniq > 1.txt
> grep 'libcpp-no-exceptions' -R . | perl -pe 's|(.*?):.*|\1|' | sort | \
uniq > 2.txt
> diff 1.txt 2.txt
This showed up a few extra interesting cases:
 These two tests do not use try/catch/throw statements, but they fail at
runtime. Need to be investigated, I've left the XFAILs in.
 These tests use a macro named TEST_HAS_NO_EXCEPTIONS to conditionally
exclude try/catch/throw statements when running without exceptions. I'm not
entirely sure why this was needed (AFAIK, we didn't have a no-exceptions
library build before). The macro's defintion is quite similar to that of
_LIBCPP_NO_EXCEPTIONS. I will investigate if this can be reused for my test
fixes or if it should be replaced with _LIBCPP_NO_EXCEPTIONS.
