Clang support for -flto=thin.

Browse Source 
Summary:
Add clang support for -flto=thin option, which is used to set the
EmitFunctionSummary code gen option on compiles.

Add -flto=full as an alias to the existing -flto.

Add tests to check for proper overriding of -flto variants on the
command line, and convert grep tests to FileCheck.
