John McCall c67067f43e Teach CFG building how to deal with CXXMemberCallExprs and BoundMemberTy,
then teach -Wreturn-type to handle the same.  Net effect:  we now correctly
handle noreturn attributes on member calls in the CFG.

Francois Pichet 3abc9b8b79 In Microsoft mode, allow pure specifier (=0) on inline functions declared at class scope.
This removes 2 errors when parsing MFC code with clang

Example:
class A {
    virtual void f() = 0 { }
}

Bill Wendling 50117f8186 Give the 'eh.sjlj.dispatchsetup' intrinsic call the value coming from the setjmp
intrinsic call. This prevents it from being reordered so that it appears
*before* the setjmp intrinsic (thus making it completely useless).

Evan Cheng 05fc35e275 Add a late optimization to BranchFolding that hoist common instruction sequences
at the start of basic blocks to their common predecessor. It's actually quite
common (e.g. about 50 times in JM/lencod) and has shown to be a nice code size
benefit. e.g.

        pushq   %rax
        testl   %edi, %edi
        jne     LBB0_2
## BB#1:
        xorb    %al, %al
        popq    %rdx
        ret
LBB0_2:
        xorb    %al, %al
        callq   _foo
        popq    %rdx
        ret

=>

        pushq   %rax
        xorb    %al, %al
        testl   %edi, %edi
        je      LBB0_2
## BB#1:
        callq   _foo

David Chisnall c2fcb4df5e Add support for plugins add passes to the default set of passes. The standard set of passes used by front ends can now be modified by LLVM plugins, without needing to modify any front ends.
Still to do:

- Allow replacing / removing passes (infrastructure there, just needs an infrastructure exposed)
- Defining sets of passes to be added or removed as a group
- Extending the support to allow user-defined groups of optimisations
- Allow plugins to be specified for loading automatically (e.g. from plugins.conf or some similar mechanism)

Johnny Chen 86f4f315ca Add TestObjCTypeQueryFromOtherCompileUnit.py to test that when stopped in the 'main.c'
compile unit, which has an external reference to symbols defined in foo.m, the type query:

    in this case, 'expression (NSArray*)array_token'

continues to work.

Matt Beaumont-Gay 5bd77b3b0f Change magic string "abc" to better magic string "qux".
Wait, what?

So, we run Clang (and LLVM) tests in an environment where the md5sum of the
input files becomes a component of the path. When testing the preprocessor,
the path becomes part of the output (in line directives). In this test, we
were grepping for the absence of "abc" in the output. When the stars aligned
properly, the md5sum component of the path contained "abc" and the test
failed. Oops.

Also add three convenience functions get_GPRs(frame), get_FPRs(frame), and get_ESRs(frame) to get the general
purpose registers, the floating point registers, and the exception state registers.

Alexis Hunt 80f00ff95d Re-do R131114 without breaking code.
I've edited one diagnostic which would print "copy constructor" for copy
constructors and "constructor" for any other constructor. If anyone is
extremely enamored with this, it can be reinstated with a simple boolean
flag rather than calling getSpecialMember, which is inappropriate.

Rafael Espindola fdc3e6fab6 Use .cfi_sections to put the unwind info in .debug_frame when possible. With
this clang will use .debug_frame in, for example,
clang -g -c -m32 test.c
This matches gcc's behaviour. It looks like .debug_frame is a bit bigger
than .eh_frame, but has the big advantage of not being allocated.

Douglas Gregor 972fe534ed Reimplement Sema::MatchTemplateParametersToScopeSpecifier() based on
the semantic context referenced by the nested-name-specifier rather
than the syntactic form of the nested-name-specifier. The previous
incarnation was based on my complete misunderstanding of C++
[temp.expl.spec]. The latest C++0x working draft clarifies the
requirements here, and this rewrite is intended to follow that.

Along the way, improve source location information in the
diagnostics. For example, if we report that a specific type needs or
doesn't need a 'template<>' header, we dig out that type in the
nested-name-specifier and highlight its range.

Fixes: PR5907, PR9421, PR8277, PR8708, PR9482, PR9668, PR9877, and
