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.

Rejigger how -pedantic and -pedantic-errors work and their interaction
...
with other diagnostic mapping. In the new scheme, -Wfoo or -Wno-foo or
-Werror=foo all override the -pedantic options, and __extension__
robustly silences all extension diagnostics in their scope.
An added bonus of this change is that MAP_DEFAULT goes away, meaning that
per-diagnostic mapping information can now be stored in 2 bits, doubling
the density of the Diagnostic::DiagMapping array. This also
substantially simplifies Diagnostic::getDiagnosticLevel.
OTOH, this temporarily introduces some "macro intensive" code in
Diagnostic.cpp. This will be addressed in a later patch.

Make the implicit-int handling error recovery stuff handle C++
...
nested name specifiers. Now we emit stuff like:
t.cpp:8:13: error: unknown type name 'X'
static foo::X P;
~~~~ ^
instead of:
t.cpp:8:16: error: invalid token after top level declarator
static foo::X P;
^
This is inspired by a really awful error message I got from
g++ when I misspelt diag::kind as diag::Kind.
