Summary:
This is the same kind of bug than [[ http://reviews.llvm.org/D18238 | D18238 ]].
Fix crashes caused by deferencing null pointer when declarations parsing may be delayed.
The body of the declarations may be null.
The crashes were observed with a Windows build of clang-tidy and the following command-line.
```
command-line switches: -fms-compatibility-version=19 -fms-compatibility
```

Going through a string removes some of the smarts of the diagnosic printer
and makes the code more complicated. This change has some cosmetic impact
on the output but that's mostly minor.

Differential Revision: http://reviews.llvm.org/D15822
llvm-svn: 256636
Summary:
The patch adds a new ClangTidy check that detects when expensive-to-copy types are unnecessarily copy initialized from a const reference that has the same or are larger scope than the copy.
It currently only detects this when the copied variable is const qualified. But this will be extended to non const variables if they are only used in a const fashion.
