and objects of this class are derived from 'NSProxy'.
Under such conditions, which means that every method possible is
implemented in the class, we should not issue "Method definition not found"
warnings.

- This is a WIP...
- This adds -march= handling to the driver, and fixes the defaulting
of -mcpu on Darwin (which was using the wrong test).
Instead of handling -m{sse, ...} in the driver, pass them to clang-cc as
-target-feature [+-]name
In clang-cc, communicate with the (clang) target to discover the legal
features of a target, and the features which are enabled based on
-mcpu. This is currently hardcoded just enough to not be a feature
regression, we need to get this information from the backend's
TableGen information somehow.
This is used to construct the full list of features which are being
used, which is in turn used to initialize the predefines.

always return a non-null QualType + error bit. This fixes a bunch of
cases that didn't check for null result (and could thus crash) and eliminates
some crappy code scattered throughout sema.
This also improves the diagnostics in the recursive struct case to eliminate
a bogus second error. It also cleans up the case added to function.c by forming
a proper function type even though the declarator is erroneous, allowing the
parameter to be added to the function. Before:
t.c:2:1: error: unknown type name 'unknown_type'
unknown_type f(void*P)
^
t.c:4:3: error: use of undeclared identifier 'P'
P+1;
^
After:
t.c:2:1: error: unknown type name 'unknown_type'
unknown_type f(void*P)
^

Several changes here:
1. We change Type::isIncompleteType to realize that forward declared
interfaces are incomplete. This eliminate special case code for this
from the sizeof path, and starts us rejecting P[4] when P is a pointer
to an incomplete interface.
2. Explicitly reject P[4] when P points to an interface in non-fragile ABI
mode.
3. Switch the sizeof(interface) diagnostic back to an error instead of a
warning in non-fragile abi mode.

This enables class recognition to work with PCH. I believe this means we can remove Sema::ObjCInterfaceDecls and it's usage within Sema::LookupName(). Will investigate.

for scoping to match C99 even when in C89 mode. This patch fixes this
(eliminating a "redefinition of thisKey" error), and also prevents non-sensical
diagnostics in -pedantic mode like this:
t.m:7:8: warning: variable declaration in for loop is a C99-specific feature
for (id thisKey in keys) ;

addRecordToClass.
- Among other things, this fixes a crash when applying sizeof to an
interface with synthesized ivars, although things still aren't
"correct" here.
