- Pulled -Xarch processing into this.

 - Get rid of manual creation of forwarding arg array.

 - Use Darwin/CC1 instead of generic GCC cc1 on X86.

DeclContext::KindTrait was not meant to be used outside of DeclContext::CastTo (causes compilation error on MSVC).
Add DeclContext::getDeclKind() and use that instead of DeclContext::KindTrait.

 - --gstabs only goes to Darwin/Assembler when dealing with an
     assembly file from the command line.

 - Relative placement of -o option for cc1 moves depending on
   -fsyntax-only/-S, how quaint.

 - Simple mechanism for group together sets of options so the driver
   can efficiently deal with them as a group (i.e., for forwarding -i*
   to cc1).

 - Use to finish off the major missing pieces of Darwin/CC1 support.

FIX llvm-gcc bootstrap on x86_64 linux. If a virtual register is copied to a physical register, it's not necessarily defined by a copy. We have to watch out it doesn't clobber any sub-register that might be live during its live interval. If the live interval crosses a basic block, then it's not safe to check with the less conservative check (by scanning uses and defs) because it's possible a sub-register might be live out of the block.

its Decls in indented format. An Example:

$ cat t.cpp
class A {
  int a;
  void f();
};
void A::f() {
  a = 3;
}

$ clang -print-decl-contexts t.cpp

    [class] A 0x9753310
        <class> A 0x975ce20

        <c++ method> f
        <c++ ctor> A
        <c++ ctor> A

Some comments: '<>' indicates a declaration, '[]' indicates a definition, '[[
]]' displays the semantic DeclContext which is different from the lexical
DeclContext.  The symbols printed can definitely be changed in the future.
