Sam Panzer, author of loop convert, provided a list of limitations of the tool
to be documented. (Thanks Sam!)

The transform's limitations are now documented in the existing user doc.
Included are examples of the cases where the tool may change semantics.

In case of macro body expansion, check to see if the macro is named NULL and
don't replace inside the macro body. This fixes the case when NULL appears
inside the macro body and the transform replaces the usage of the macro with
nullptr. This is an easy fix for the problem for now and we should analyze the
macro body to see if it expands to only NullToPointer in the future for a more
robust solution that takes care of user defined macros that behaves like NULL.

Other changes:
- Moved complex macro tests to macros.cpp
- Added new test cases.
- Added checks to make sure that the macro bodies are not modified by the tool.

The outer-most explicit cast is now left alone by the Use-Nullptr transform to
maintain the type of the expression and avoid introducing ambiguities.

Fixes PR15395.

Author: Ariel J Bernal <ariel.j.bernal@intel.com>
llvm-svn: 177179

The Use-Nullptr transform was replacing nullptr_t-typed expressions because in
the AST such expressions have an implicit NullToPointer cast around them. Now
the transform ignores these expressions.

For iterators where the dereference operator returns by value, LoopConvert
should use 'auto &&' in the range-based for loop expression.

If the dereference operator returns an rvalue reference, this is deemed too
strange and the for loop is not converted.

Moved test case from iterator_failing.cpp to iterator.cpp and added extra
tests.

Fixes PR15437.

NOTE: You may need to run 'make clean' or 'ninja -t clean' etc!!! This
      is due to really nasty bug/interactions between
      CMake/configure/make/Ninja/LIT...

This commit tries to back out the support for generating test cases as
part of the build system due to the issues I brought up in post-commit
review:

1) It adds a *lot* of complexity and fragility to the build system. See
   the number of commits required to try to get all the bots happy.
2) It isn't really necessary -- we can already run scripts to generate
   things with the RUN lines of a test.
3) It makes the tests somewhat harder to debug as they cross between
   more domains.
4) In almost all cases it isn't really needed or it can be done directly
   using the preprocessor.

I should have been more proactive reviewing this, and I'm really sorry
about the churn here. =/ To help keep track of what commits are going
where, this backs out most of the non-test-changes from these revisions:
  r176397
  r176373
  r176293
  r176184
  r175744
  r175624
  r175545
  r175544

There were several trivial or cleanup changes to the lit files or other
files. Some of these looked ok, but I didn't try to tease them apart...
Edwin, if you know what to look for, please carry on with the cleanups
there, and sorry for hosing stuff here but I'm not much of a Python
person, and so I was erring on the side of cautiously backing out the
change.

I've tried to preserve the test changes everywhere I could, but review
is appreciated here in case I missed some.

I then re-wrote the tests to use the preprocessor rather than python to
expand to the various bits of code. The nicest part of this is that now
all the files are just C++ code. They edit and behave like C++ code,
etc. RUN lines with different -D flags are used to run the same test
over multiple different configurations, and includes bracketed in
special defines are used to flesh out a collection of standard interface
stubs to test interactions between pieces. These probably aren't perfect
yet, but I think its an improvement (at least in terms of build system
complexity) and will hopefully be a useful demonstration of the
technique I prefer for these types of tests.

The use-null-ptr transform will transform calls to functions that return a
nullptr_t. Even if the function were to only return a null pointer and do
nothing else, this replacement would still be undesired as the behavior and
signature of the function could change in the future.

This adds an XFAILed test case to demonstrate the issue.

LoopConvert isn't properly handling iterators whose dereference operator
