[BRIGFE] Enable whole program optimizations
visit0r: HSA assumes all program scope HSAIL symbols can be queried from the host runtime API, thus cannot be removed by the IPA. Getting some inlining happening in the finalized binary required: - explicitly marking the 'prog' scope functions and the launcher function "externally_visible" to avoid the inliner removing it - also the host_def ptr is set to externally visible, otherwise IPA assumes it's never set - adding the 'inline' keyword to functions to enable inlining, otherwise GCC defaults to replaceable functions (one can link over the previous one) which cannot be inlined - replacing all calls to declarations with calls to definitions to enable the inliner to find the definition - to fix missing hidden argument types in the generated functions.
