more cleanups, refactor HandleVectorTypeAttribute

it to HandleVectorSizeAttribute to match its attr name.
No functionality change.

adjust the prototypes of a bunch of decl processing methods to take
the single attribute they look at by reference instead of by pointer.
This is a subtle indicator that they take the specified attribute, not
a whole list of them.
This also make HandleExtVectorTypeAttribute work the same way as the rest
of the attributes, adds some comments etc. No functionality change.

Fix for PR2501; this patch makes usual arithmetic conversions for
integers which have the same width and different signedness work
correctly. (The testcase in PR2501 uses a comparison between long and
unsigned int).
Replace CurFunctionDecl and CurMethodDecl with methods getCurFunctionDecl() and getCurMethodDecl() that return the appropriate Decl through CurContext.

fix a bug handling type attributes in the declspec. declspec processing

Note that Parser::ParseCXXMemberSpecification is temporarily disabled until the Sema support is in place.
Once ParseCXXMemberSpecification is enabled, the Parser/cxx-class.cpp test will pass.

ObjCMessageExpr objects that represent messages to class methods now can contain the ObjCInterfaceDecl* of the target class if it was available when the ObjCMessageExpr object was constructed. The original interfaces of the class has been preserved (requiring no functionality changes from clients), but now a "getClasSInfo" method returns both the ObjCInterfaceDecl* and IdentifierInfo* of the target class.

'There's not much to say about this patch, it just adds the Arch Linux
gcc 4.3.1 header paths for i686 and amd64. The patch was generated
using "svn diff" with clang at revision 52660. The paths aren't
distribution-specific, so they should work for all Linux distributions

Added ObjCSummaryCache, a new summary cache object to cache summaries for Objective-C methods. Instead of mapping from Selectors -> Summaries, we will now map from (ObjCInterfaceDecl*,Selectors) -> Summaries. This will allow more nuanced summary generation. This patch just swaps in the new data structure; the rest of the code works as before by allowing the ObjCInterfaceDecl* to be null.

"this patch adds code generation hooks for Objective-C constant strings. It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet."

"This maps the -pthread option to -lpthread - this isn't 100% correct,
since handling this correctly is quite complex, and on some platforms
requires additional -D options and on some implies linking against a
different libc, but this works better than just ignoring the option.
The other change passes the -x option across to clang, which allows
compiling .c files as Objective-C and so on. For some reason a lot of
configure scripts seem to be under the misguided impression that this
is a sensible thing to do."

Modified the dead stores checker to...
1) Check if a dead store appears as a subexpression. For such cases, we emit
a verbose diagnostic so that users aren't confused. This addresses:

2) Don't emit a dead store warning when assigning a null value to a pointer.
This is a common form of defensive programming. We may wish to make
this an option to the the checker one day.
