Fariborz Jahanian a2d7c34e93 Fixed a block regression caused by trying to use 
an existing ir for load of a bock variable. This cannot be
done across basic blocks.
Fixes radar 8064140.

Fariborz Jahanian 64176c2c97 For C++ copied in objects, use copy constructors in 
setting up block's descriptor. This is on going work to
support c++ specific issues in setting up blocks
various APIs.

John McCall 9d42f0f174 Allocate space in a block record for implicit references to the Objective C 
'self' variable arising from uses of the 'super' keyword.  Also reorganize
some code so that BlockInfo (now CGBlockInfo) can be opaque outside of
CGBlocks.cpp.

Fixes rdar://problem/8010633.

John McCall 87fe5d5618 Support implicitly closing on 'this' in a block. Fixed PR7165. 
(the codegen works here, too, but that's annoying to test without execution)

John McCall 2188696d98 Miscellaneous codegen cleanups. Mostly, don't create new basic blocks 
just to save the current insertion state!  This change significantly
simplifies the IR CFG in exceptions code.

Blaine Garst f27ab71d9f add support for a 1<<29 bit in the block flags field to mark blocks using alternate struct return ABI

Blaine Garst fc83aa04db Unconditionally support block introspection data in a new field at the end 
of the block descriptor field.  This field is the ObjC style @encode
signature of the implementation function, and was to this point
conditionally provided in the block literal data structure.  That
provisional support is removed.

Additionally, eliminate unused enumerations for the block literal flags field.
The first shipping ABI unconditionally set (1<<29) but this bit is unused
by the runtime, so the second ABI will unconditionally have (1<<30) set so
that the runtime can in fact distinguish whether the additional data is
present or not.

Ken Dyck 40775003e6 Roll out ASTContext::getTypeSizeInChars(), replacing instances of 
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate. 

Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, 
fromQuantity(), and getQuantity() for clarity.

David Chisnall 950a9518b1 Added block type introspection support. 
As per Fariborz's suggestion, committed now but can be reverted later if the used flag is problematic for Apple.

Mike Stump cbc2bcaf17 As an optimization, we maintain a cache of generated 
___Block_byref_id_object_dispose and ___Block_byref_id_object_copy
functions so that we can simply reuse instead of creating a new one.
Additionally, add an assert to ensure no one yet tries to align a
__block variable beyond the alignment of a pointer as the codegen is
incomplete.

Daniel Dunbar 0a2171ccd5 Skip the asm prefix when storing the name in block info. 
- Otherwise we emit internal names with embedded '\01' characters,
   which confuses some tools.

 - Ideally all the code which wants to get a "display name" for the
   given function should follow one code path, but this should be a
   monotonic improvement for now.

Mike Stump 95435674f9 Move more of blocks codegen out of CodeGenModule and into the

don't want to know anything about blocks not be confused by the
overloaded use of the term block or nor want to see all the blocks
goop.
