John McCall 9e2e22f5c6 Establish the iteration variable of an ObjC for-in loop before 
emitting the collection expression.  Fixes some really, really broken
code.

John McCall a9a2e8a58d The flags we're supposed to write into a byref struct are *not* the 
_Block_object_* flags;  it's just BLOCK_HAS_COPY_DISPOSE or not.

Also, we don't need to chase forwarding pointers prior to calling
_Block_object_dispose;  _Block_object_dispose in fact already does
this.

John McCall bf9a86b50f Don't call objc_read_weak as part of emitting a block literal. 
Nobody ever gave me a clear reason for why we were doing this, and
now it's apparently causing serious problems, so if *not* having this
causes problems, we get to solve them the right way this time.

John McCall 351762cda2 A few more tweaks to the blocks AST representation: 
- BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

Ted Kremenek 1d56c9eed7 Add -fobjc-default-synthesized-properties flag 
to allow us to explicitly control whether or
not Objective-C properties are default synthesized.
Currently this feature only works when using
the -fobjc-non-fragile-abi2 flag (so there is
no functionality change), but we can now turn
off this feature without turning off all the features
coupled with -fobjc-non-fragile-abi2.

John McCall 0692a32a3e Test case for the l-value base only being evaluated once. 
Also, move the l-value emission code into CGObjC.cpp and teach it, for
completeness, to store away self for a super send.

Also, inline the super cases for property gets and sets and make them
use the correct result type for implicit getter/setter calls.
