clang: updated to 9.0.0

9.0.0:
Major New Features
* Experimental support for C++ for OpenCL has been added.

Non-comprehensive list of changes in this release
* The __VERSION__ macro has been updated. Previously this macro contained the string ‘4.2.1 Compatible’ to achieve compatibility with GCC 4.2.1, but that should no longer be necessary. However, to retrieve Clang’s version, please favor the one of the macro defined in clang namespaced version macros.

New Compiler Flags
* -ftime-trace and ftime-trace-granularity=N Emits flame chart style compilation time report in chrome://tracing and speedscope.app compatible format. A trace .json file is written next to the compiled object file, containing hierarchical time information about frontend activities (file parsing, template instantiation) and backend activities (modules and functions being optimized, optimization passes).

Modified Compiler Flags
* clang -dumpversion now returns the version of Clang itself.

Windows Support
* clang-cl now treats non-existent files as possible typos for flags, clang-cl /diagnostic:caret /c test.cc for example now produces clang: error: no such file or directory: '/diagnostic:caret'; did you mean '/diagnostics:caret'?
* clang now parses the __declspec(allocator) specifier and generates debug information, so that memory usage can be tracked in Visual Studio.
* The -print-search-dirs option now separates elements with semicolons, as is the norm for path lists on Windows
* Improved handling of dllexport in conjunction with explicit template instantiations for MinGW, to allow building a shared libc++ for MinGW without --export-all-symbols to override the dllexport attributes
