    A clang/test/CodeGen/windows-seh-async-exceptions.cpp

  Log Message:
  -----------
  Fix assertion when -fasy-exception is used.

The assertion only happens with use of -fasy-exception without
-fexcessions.

The assertion appen during the call to generate SehScopeBegin(), where
assert with:
assert(CGF.Builder.GetInsertBlock() && InvokeDest);
InvokeDest is null. Because exceptions are disabled, and SEH is not
in use.
The fix is before call EmitSehCppScopeBegin check getInvokeDest(),
to avoid assert during the emit llvm.seh.scope.begin()
