characters or other regex control characters.

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).

cmp-and-swap reversed the Cmp and Swap arguments; comments
make it clear this is unintentional.  Unfortunately, the
x86 BE had a compensating reversal, which is removed here.
PPC is OK.

From inspection of the Alpha code I think it is OK, but
if somebody has that platform please check it out.  I
cannot test on that platform.

 - Added ABIArgInfo::ByVal (mostly supported) and ABIArgInfo::Expand
   (asserted out).

 - Added classifyArgumentType which currently just uses
   ABIArgInfo::Default or ByVal. This nearly matches old behavior, but
   we now set ByVal in a few situations we may have left it off before
   (on complex, for example).
