Don't try to generate common globals for C++ files, instead of depending on the FE to set NoCommon, and simplify CodeGenOptions initialization.

stat a file but where mmaping it fails.  In this case, we emit an
error like:
t.c:1:10: fatal error: error opening file '../../foo.h'

instead of "cannot find file".

 - Clients that care about having the diagnostics output honor the user-controllable diagnostic options can buffer the diagnostics and issue them later.

Change CompilerInvocation::CreateFromArgs to take Argv0 and the address of main (or something in the main executable) so it can find the builtin compiler files.

Don't call Decl::CollectingStats(false) and Stmt::CollectingStats(false). When called with false these functions return whether statistics are enabled. They don't change any state. Since we're not using the return value avoid calling them in the first place.

CompilerInstance already contains various objects that are used
throughout the entire run.

function names outside of templates - they'll probably cause some damage there as
they're largely untested.

Move LLVM backend options to explicit clang-cc / clang -cc1 options, which we then manually pass to the command line library; eventually the latter grossness should be fixed by a real API when creating the target machine.

DeclarationName can't handle them yet, so right now Parser just errors out on them.
