using getValue instead of getAPIntValue.

I placed it just before GVN because that it is the
pass most likely to benefit from it.  Some quick
and dirty testing confirms that this is a decent
place for it.

when a readonly declaration is called, set a
flag.  This is faster and uses less memory.
In theory it is less accurate, because before
only those internal globals that were read
by someone were being marked "Ref", but now
all are.  But in practice, thanks to other
passes, all internal globals of the kind
considered here will be both read and stored
to: those only read will have been turned
into constants, and those only stored to will
have been deleted.

 - Follow C99 behavior of using other operand type when one of
   operands is a null pointer constant.
 - Fix overenthusiastic devolving of any Objective-C types to id:
   o If either operand has an Objective-C object type then:
     - If both operands are interfaces and either operand can be
       assigned to the other, use that type as the composite type.
     - Otherwise, if either type is id, use id as the composite type.
     - Otherwise, warn about incompatible types and use id as the
       composite type.
 - Return handling of qualified idea to separate test following
   general pointer type checking.
   o Upgraded from old code to allow devolving to id (without warning,
     which matches GCC).

Add test case for issues fixed above, XFAIL though because it exposed
a new issue in property handling.

Fix PR2748. Avoid coalescing physical register with virtual register which would create illegal extract_subreg. e.g.
vr1024 = extract_subreg vr1025, 1
...
vr1024 = mov8rr AH
If vr1024 is coalesced with AH, the extract_subreg is now illegal since AH does not have a super-reg whose sub-register 1 is AH.

way. TableGen sorts the records that will be used to create it by the names 
of the records, not the Name field of those records.

This patch corrects the sort to use the "Name" field of the record as the 
sort key.

Fix <rdar://problem/6210791> clang ObjC rewriter: @try / @catch block with no @finally does not call objc_exception_try_exit.

Need a couple tweaks to RewriteObjCTryStmt(). Need to deal with implicit finally clauses (to make sure objc_exception_try_exit is called). Also fixed a related bug where we need to generate an implicit @catch else clause (to again make sure objc_exception_try_exit is called).
