David Chisnall 7b36a86431 [gnustep-objc] Make the GNUstep v2 ABI work for Windows DLLs.
Summary:
Based on a patch by Dustin Howett, modified to not change the ABI for
ELF platforms.

Use more Windows-like section names.

This also makes things more readable by PE/COFF debug tools that assume
sections fit in the first header.

With these changes in, it is now possible to build a working WinObjC
with clang and the WinObjC version of GNUstep libobjc (upstream GNUstep
libobjc + a work around for incremental linking, which can be removed
once LINK.EXE gains a feature to opt sections out of receiving extra
padding during an incremental link).

David Chisnall 0e9e02cd72 [objc-gnustep] Use .init_array not .ctors when requested.
This doesn't make a difference most of the time but FreeBSD/ARM doesn't
run anything in the .ctors array.

Nico Weber 346f1e97a9 Fix a few tests that were missing ':' on CHECK lines and weren't testing anything.
Found by `git grep '\/\/ CHECK-[^: ]* ' clang/test/ | grep -v RUN:`.

Also tweak CodeGenCXX/arm-swiftcall.cpp to still pass now that it checks more.

Douglas Yung 9b6cd711d6 Make the section boundary checks on Windows not depend on the order as they are emitted in reverse when the compiler is built by Visual C++.

David Chisnall 93ce018f3d Add Windows support for the GNUstep Objective-C ABI V2.
Summary:
Introduces funclet-based unwinding for Objective-C and fixes an issue
where global blocks can't have their isa pointers initialised on
Windows.

After discussion with Dustin, this changes the name mangling of
Objective-C types to prevent a C++ catch statement of type struct X*
from catching an Objective-C object of type X*.

David Chisnall 45d0a2650e [objc-gnu] Fix test.
The test was implicitly capturing the local filesystem layout.

Bjorn Pettersson 844663353d Revert r332955 "GNUstep Objective-C ABI version 2"
Reverted due to buildbot failures.
Seems like isnumber() is some Apple addition to cctype.

David Chisnall 79356eefc0 GNUstep Objective-C ABI version 2
Summary:
This includes initial support for the (hopefully final) updated Objective-C ABI, developed here:

https://github.com/davidchisnall/clang-gnustep-abi-2

It also includes some cleanups and refactoring from older GNU ABIs.

The current version is ELF only, other formats to follow.
