[cfe-commits] have the preprocessor take ownership of callback objects

[Sam Bishop]

The attached patch fixes a memory leak by having Preprocessor objects
take ownership of any PPCallbacks objects they're given.  I can't think
of any reason why their lifetimes would be different.

Together with the TargetInfo patch, "echo 'int main() {}' | clang -E" is
now valgrind-clean.
