Explictly track tentative definitions within Sema, then hand those

tentative definitions off to the ASTConsumer at the end of the

Eliminate CodeGen's internal tracking of tentative definitions, and
instead hook into ASTConsumer::CompleteTentativeDefinition. Also,
tweak the definition-deferal logic for C++, where there are no
tentative definitions.
Fixes <rdar://problem/6808352>, and will make it much easier for
precompiled headers to cope with tentative definitions in the future.

statements don't end up in the LabelMap so we don't have a quick way

rewrite the goto scope checking code to be more efficient, simpler,
...
produce better diagnostics, and be more correct in ObjC cases (fixing
rdar://6803963).
An example is that we now diagnose:
int test1(int x) {
goto L;
int a[x];
int b[x];
L:
return sizeof a;
}
with:
scope-check.c:15:3: error: illegal goto into protected scope
goto L;
^
scope-check.c:17:7: note: scope created by variable length array
int b[x];
^
scope-check.c:16:7: note: scope created by variable length array
int a[x];
^
instead of just saying "invalid jump". An ObjC example is:
void test1() {
goto L;
@try {
L: ;
} @finally {
}
}
t.m:6:3: error: illegal goto into protected scope
goto L;
^
t.m:7:3: note: scope created by @try block
@try {
^
There are a whole ton of fixme's for stuff to do, but I believe that this
is a monotonic improvement over what we had.

tweak redefinition of a typedef a bit to fix a couple of problems:
...
1. We had logic in sema to decide whether or not to emit the error
based on manually checking whether in a system header file.
2. we were allowing redefinitions of typedefs in class scope in C++
if in header file.
3. there was no way to force typedef redefinitions to be accepted
by the C compiler, which annoys me when stripping linemarkers out
of .i files.
The fix is to split the C++ class typedef redefinition path from the
C path, and change the C path to be a warning that normally maps to
error. This causes it to properly be ignored in system headers,
etc. and gives us a way to control it. Passing
-Wtypedef-redefinition now turns the error into a warning.
One behavior change is that we now diagnose cases where you redefine
a typedef in your .c file that was defined in a header file. This
seems like reasonable behavior, and the diagnostic now indicates that
it can be controlled with -Wtypedef-redefinition.
