[cfe-dev] CompilerInstance and setting compiler options

[Alex L via cfe-dev]

I think that you can use `clang::createInvocationFromCommandLine` to parse
your compiler arguments into an instance of CompilerInvocation. Then you
can call `CompilerInstance::setInvocation` to update the invocation in your
compiler instance.

I hope that helps,
Alex
