Recommit r222044 with a test fix - it does not make sense to hunt
for a typedef before arithmetic conversion in all rare corner cases.

[c++1z] Support [[deprecated]] attributes on namespaces. Note that it only applies to situations where the namespace is mentioned. Thus, use on anonymous namespaces is diagnosed.

This patch fixes couple of bugs for predefined expression
used inside blocks. It fixes a crash in naming code
for __func__ etc. when used in a block declared globally.
It also brings back old naming convention for
predefined expression which was broken. rdar://18961148

Fix IRGen for passing transparent unions

We have had a test for this for a long time with a FIXME saying what we
should be doing. This just does it.

Fixes PR21573.

Fix issues missed during the review of r222099.

Shift some functions around, make a method in Sema private,
call the correct overloaded function.  No functional change.

[Sanitizer] Parse and produce all sanitizer-relevant arguments in SanitizerArgs.

In particular, make SanitizerArgs responsible for parsing
and passing down to frontend -fsanitize-recover and
-fsanitize-undefined-trap-on-error flags.

Simplify parsing -f(no-)sanitize= flags parsing: get rid of
too complex filterUnsupportedKinds function.

No functionality change.

Remove VariadicOperatorMatcherInterface as it is redundant with logic from DynTypedMatcher.

Summary:
The generic variadic matcher is faster (one less virtual function call
per match) and doesn't require template instantiations which reduces
compile time and binary size.
Registry.cpp.o generates ~14% less symbols and compiles ~7.5% faster.
The change also speeds up our clang-tidy benchmark by ~2%.
