gcc49-pr57620.patch

So far only very lightly tested patch, passes raw-string* tests (except for
raw-string-2.c which contains also trigraph tests that were valid in the
earlier raw string paper, but aren't valid in C++11) and this plus a few other
tests.
Will still need to adjust raw-string-2.c, and add sufficient test coverage for
all the corner cases.
