We already reject flags that don't have the CC1Option flag,
but we would previously do so after parsing the command-line
arguments.

CC1: Only parse command-line options that have the CC1Option flag.

We already reject flags that don't have the CC1Option flag,

arguments.

Since the option parser now has a parameter for excluding options,
we should just use that instead.

follow.

Fix a leak of TargetMachine in clang. We'll continue to leak it on purpose if
given -disable-free. (Reviewed by John McCall over IRC.)

[Driver] Refactor clang driver to use LLVM's Option library

The big changes are:
- Deleting Driver/(Arg|Opt)*
- Rewriting includes to llvm/Option/ and re-sorting
- 'using namespace llvm::opt' in clang::driver
- Fixing the autoconf build by adding option everywhere

As discussed in the review, this change includes using directives in
header files. I'll make follow up changes to remove those in favor of
name specifiers.

Per discussion in cfe-commits, asserting may be a better way than introducing a special test flag.

[driver] Improve the implementation of the -Ofast option.

Specifically, allow the flags that fall under this umbrella (i.e., -O3,
-ffast-math, and -fstrict-aliasing) to be overridden/disabled with the
individual -O[0|1|2|s|z]/-fno- flags.

This also fixes the handling of various floating point optimization
flags that are modified by -ffast-math (and thus -Ofast as well).

[Modules] Convert module specific -fno-modules-autolink into -fno-autolink.

when we support them).
