The dependency mechanism for C has been implemented, and we have rolled out
this to all internal users, didn't see crashy issues, we consider it is stable
enough.

The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

which tries to do better error recovery when it is "obvious" that an
identifier is a mis-typed typename. In this case, we try to parse
it as a typename instead of as the identifier in a declarator, which
gives us several options for better error recovery and immediately
makes diagnostics more useful. For example, we now produce:
t.c:4:8: error: unknown type name 'foo_t'
static foo_t a = 4;
^
instead of:
t.c:4:14: error: invalid token after top level declarator
static foo_t a = 4;
^
Also, since we now parse "a" correctly, we make a decl for it,
preventing later uses of 'a' from emitting things like:
t.c:12:20: error: use of undeclared identifier 'a'
int bar() { return a + b; }
^
I'd really appreciate any scrutiny possible on this, it
is a tricky area.
