Add support for /Ob1 (and equivalent -finline-hint-functions), which enable inlining only for functions marked inline, either explicitly (via inline keyword, for example), or implicitly (function definition in class body, for example). This works by enabling inlining pass, and adding noinline attribute to every function not marked inline. Patch by Rudy Pons <rudy.pons@ilod.org>!
