This patch moves the parsing of `{Lang,CodeGen}Options` from `parseSimpleArgs` to the original `Parse{Lang,CodeGen}Args` functions.
This ensures all marshalled `LangOptions` are being parsed **after** the call `setLangDefaults`, which in turn enables us to marshall `LangOptions` that somehow depend on the defaults. (In a future patch.)
Now, `CodeGenOptions` need to be parsed **after** `LangOptions`, because `-cl-mad-enable` (a `CodeGenOpt`) depends on the value of `-cl-fast-relaxed-math` and `-cl-unsafe-math-optimizations` (`LangOpts`).
Unfortunately, this removes the nice property that marshalled options get parsed in the exact order they appear in the `.td` file. Now we cannot be sure that a TableGen record referenced in `ImpliedByAnyOf` has already been parsed. This might cause an ordering issues (i.e. reading value of uninitialized variable). I plan to mitigate this by moving each `XxxOpt` group from `parseSimpleArgs` back to their original parsing function. With this setup, if an option from group `A` references option from group `B` in TableGen, the compiler will require us to make the `CompilerInvocation` member for `B` visible in the parsing function for `A`. That's where we notice that `B` didn't get parsed yet.

This mimics FileCheck's --check-prefixes option.
The default prefix is "expected". That is, "-verify" is equivalent to
"-verify=expected".
The goal is to permit exercising a single test suite source file with different
compiler options producing different sets of diagnostics. While cpp can be
combined with the existing -verify to accomplish the same goal, source is often
easier to maintain when it's not cluttered with preprocessor directives or
duplicate passages of code. For example, this patch also rewrites some existing
clang tests to demonstrate the benefit of this feature.

The frontend currently groups diagnostics from the command line according to
diagnostic level, but that places all notes last. Fix that by emitting such
diagnostics in the order they were generated.
