Our support for C++ EH is sufficiently good that it makes sense to
enable support for it out of the box.

While we are here, update the MSVCCompatibility doc.

[sanitizer-coverage] allow -fsanitize-coverage=trace-pc w/o any other sanitizer and w/o ...=[func,bb,edge]. This makes this syntax a superset of the GCC's syntax

[sanitizer-coverage] implement -fsanitize-coverage=trace-pc. This is similar to trace-bb, but has a different API. We already use the equivalent flag in GCC for Linux kernel fuzzing. We may be able to use this flag with AFL too

After some experiments I discovered that clang doesn't support static
initialization of flexible array members in full, so restored this paragraph in
"GCC extensions not implemented yet" list.

#pragma weak, global register variables and static initialization of flexible
array members are supported now, so they are removed from "GCC extensions not
implemented yet" list.

This builds on the support being added to LLVM to import and export
registries from DLLs.  This will allow us to pick up the registry
entries added in the DLL's copy of FrontendPluginRegistry.

This will allow us to use plugins on Windows using:
$ clang-cl -Xclang -load -Xclang plugin.dll \
           -Xclang -add-plugin -Xclang foo

Summary:
MSVC's driver accepts all unknown arguments but warns about them.  clang
by default rejects all unknown arguments.  This causes issues
specifically with build systems such as autoconf which liberally pass
things such as $LDFLAGS to the compiler and expect everything to work.
This patch teaches clang-cl to ignore unknown driver arguments.

When dumping documentation for AST matchers, do something more useful with \see doxygen commands. Ideally this would link to the target of \see, but for now it translates \see into "See also: "
