Summary: A checker (will be uploaded after this patch) needs to check implicit casts. Existing generic matcher "has" ignores implicit casts and parenthesized expressions and no specific matcher for matching return value expression preexisted. The patch adds such a matcher (hasReturnValue).

This patch adds a regular expression to configure suffixes of an
included file to check whether it is the "main" include of the current
file. Previously, clang-format has allowed arbitrary suffixes on the
formatted file, which is still the case when no IncludeMainRegex is
specified.

Currently when an AST plugin is loaded it must then be enabled by passing
-plugin pluginname or -add-plugin pluginname to the -cc1 command line. This
patch adds a method to PluginASTAction which allows it to declare that the
action happens before, instead of, or after the main AST action, plus the
relevant changes to make the plugin action happen at that time automatically.

Original patch by Stefan Bühler http://reviews.llvm.org/D12834

Difference between original and this one:
- fixed all comments in original code review
- added more tests, all new diagnostics now covered by tests
- moved abi_tag on re-declaration checks to Sema::mergeDeclAttributes
  where they actually may work as designed
- clang-format + other stylistic changes

Mangle part will be sent for review as a separate patch.

[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

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
