This bug was present all along, but something changed in the order
of de-initialisation performed by llvm that makes it actually
crash now.
The constructor of HipifyPPCallbacks gives:
```
std::unique_ptr<HipifyPPCallbacks>(this)
```
to the LLVM Preprocessor instance. The Preprocessor instance
subsequently frees the HipifyPPCallbacks, which is then freed
again when we leave the stack frame at line 4340.
So: let's leak the HipifyPPCallbacks onto the heap, and leave
the LLVM Preprocessor object responsible for tidying it up.
[ROCm/hip commit: f5b273fc4f]
The Preprocessor smart pointer is held by the CompilerInstance,
and therefore its reference count cannot reach zero until the
CompilerInstance itself is destroyed.
If the CompilerInstance is destroyed, you have more to worry about
than just the preprocessor being deallocated!
Newer versions of the LLVM/Clang API migrated to using
std::shared_ptr, so there is no `Retain()` function (by that
name, anyway). Eliminating this redundant use is a neat and
backward-compatible way to become compatible with newer versions
of the LLVM/Clang API.
[ROCm/hip commit: 0953a7887d]
Newer versions of llvm/clang mean there is both an
llvm::StringLiteral and a clang::StringLiteral. Since we're
dumping both namespaces wholesale into the global namespace with
`using` declarations, this creates a name collision, which must be
resolved.
This change is backwards-compatible, and fixes a problem you
encounter when using newer versions of the llvm/clang API.

What we actually want to do here is use the StringRef version in
versions newer than 3.8, and the void one in 3.8 and older.
Checking "major-version >= 3 && minor-version >= 9" does not do
what we want. Consider what this will do for version 4.0, for
which minor-version is zero...

PythonInterp is a finder module that ships with cmake. It supports
the conventional interaction with find_package that allows you
to demand success, and particular vesions, without having your
own logic:

This copies to the output after operation, instead of working
_on_ the output. This allows includes to work correctly, while
supporting output paths anywhere on the filesystem.

[Synopsis]
If any of kernel arguments is a MACRO its location calculation is wrong (location of its definition is actually calculated).
Thus garbage code is being produced on the place of such a MACRO starting from the end of its actual definition.
[Solution]
Add isMacroBodyExpansion and isMacroArgExpansion checks on kernel arguments.
