Handle PredefinedExpr with templates and lambdas

Summary:

- lambdas, blocks or captured statements in templates were not
  handled which causes codegen crashes.

This removes __has_feature(objc_msg_lookup_stret), as it is not required

Emit an error when attempting to generate IR for SEH __try

Currently we silently omit the code in the try and finally bodies, which
is pretty bad.  This way we fail loudly.

[-cxx-abi microsoft] Correctly identify Win32 entry points

Summary:
This fixes several issues with the original implementation:
- Win32 entry points cannot be in namespaces
- A Win32 entry point cannot be a function template, diagnose if we it.
- Win32 entry points cannot be overloaded.
- Win32 entry points implicitly return, similar to main.

clang-cl: ignore compile-only options in link-only invocations.

Previously we would warn about unused arguments such as /MD when linking.
Clang already has logic to ignore compile-only options, e.g. for -D and -U.
This patch extends that to include clang-cl's compile-only options too.

Also, some clang-cl options should always be ignored. Doing this earlier
means they get ignored both for compilation and link-only invocations.

Fix test/Driver/cl-options.c test

The test builds an object file to be able to get into linking mode
with a valid obj file on the command-line. Using clang-cl for this,
which targets win32, caused problems on some buildbots, so just
use regular clang.
