Fix for #403.

This improves the special case handling of passing nil in return values to handle
C++ cases that previously weren't working.

Adds tests for C++11 and C++98 variants. To test fully tests need to be executed in both
32bit and 64 bit modes.

At this stage I am not sure whether to merge a few more (#419, #404, #398) and release as 3.6.1 or whether to include #421 (and maybe a variation on #394) and then release as 3.7.

Anyone have any comments on this one? I think it's a no-brainer.

Oops.. looks like Erik is looking at it as I type :) Apologies.

Erik, do you have any plans you could share with regards to timing for OCMock 3.7, 3.8 etc? My pile of patches on my end is becoming a little scary :)

So, the plan was/is to get out 3.7 very soon. I got sidetracked by the PR's regarding Swift Package Manager, but I have now concluded that they won't be in 3.7. So, there's only two open PR's which seem reasonably straight-forward. I was also debating with myself whether #398 should be in, but I haven't read all the comments over there in detail.

This change breaks the build for me. When I change the file type back to Objective-C it works. The error is:

/Users/erik/Projects/OCMock/Repositories/ocmock/Source/OCMockTests/OCMockObjectRuntimeTests.m:219:54: error: cannot initialize a parameter of type 'void *' with an lvalue of type 'const char [4]'
XCTAssertNoThrow([[myMock expect] aSpecialMethod:"foo"], @"Should not complain about method with type qualifiers.");

ahh.. that is probably an accidental mod when I changed the file to objc++ before I broke the tests out into their own files. No need to pull that across. Apologies.

I changed these tests to pass NULL and 0 for the last two arguments. Couldn't see a reason why not, and it saved creating the value in the test.
