This should improve source fidelity, as well as being generically
useful for diagnostics and such.

Remove warnings of constant operands of logical operators from template instantiations.  Upon instantiation of template, value-dependent parameters are replaced by equivalent literals, so code like:

template<unsigned int A, unsigned int B> struct S {
  int foo() {
    int x = A && B;
  }
}

will not warn on A && B on every instantiation.  This will still warn on other cases inside templates, which will be caught on checking the template definition.

Revert "For C++11, do more checking of initializer lists up-front, enabling some subset of the final functionality. C just leaves the function early. C++98 runs through the same code path, but has no changed functionality either."

For C++11, do more checking of initializer lists up-front, enabling some subset of the final functionality. C just leaves the function early. C++98 runs through the same code path, but has no changed functionality either.
This is a first baby step towards supporting generalized initializer lists. This also removes an aggregate
test case that was just plain wrong, assuming that non-aggregates couldn't be initialized with initializer lists
in C++11 mode.

I had to bite the bullet and actually add a debugger support mode for this
one, which is a bit unfortunate, but there really isn't anything else
I could imagine doing;  this is clearly just debugger-specific behavior.

[ARC] Complain about property without storage attribute when @synthesizing it, not at its declaration.

For this sample:

@interface Foo
@property id x;
@end

we get:

t.m:2:1: error: ARC forbids properties of Objective-C objects with unspecified storage attribute
@property  id x;
^
1 error generated.

The error should be imposed on the implementor of the interface, not the user. If the user uses
a header of a non-ARC library whose source code he does not have, we are basically asking him to
go change the header of the library (bad in general), possible overriding how the property is
implemented if he gets confused and says "Oh I'll just add 'copy' then" (even worse).

Second issue is that we don't emit any error for 'readonly' properties, e.g:

@interface Foo
@property (readonly) id x; // no error  here
@end

@implementation Foo
@synthesize x; // no error here too
@end

We should give an error when the implementor is @synthesizing a property which doesn't have
any storage specifier; this is when the explicit specifier is important, because we are
going to create an ivar and we want its ownership to be explicit.

Related improvements:
-OBJC_PR_unsafe_unretained turned out to not fit in ObjCPropertyDecl's bitfields, fix it.
-For properties of extension classes don't drop PropertyAttributesAsWritten values.
-Have PropertyAttributesAsWritten actually only reflect what the user wrote
