- Function CreateTargetInfo() has an access to language options which makes target immutable after creation without modification of language options themselves. Target specific hook TargetInfo::adjustAccordingToLangOpts() can be used if such modification depends on certain target.

- Introduce LangOptions::adjustAccordingToTI() to apply changes to language options based on target info (also without modification of target info). This also involves adding of some hooks (hasAtomics() / hasAltivec() as this options are used in PPC and WebAssembly in original TargetInfo::adjust()) which potentially can be reused.

- Validation of OpenCL target is in CreateTargetInfo() as language options are available at that point.
