I tested your branch. Several observations:
(1) make worked, (I used gmp, mpfr and mpc without patches for them, there
libtool is also outdated, but I'm not sure whether it has any influence)
(2) make check did not work because of the first error below.
(3) make install did produce an error, strangely enough, as make worked without
problem.
(4) I checked that on my system there is an older version of libasan installed.
I thought this comes with every gcc installation, but apparently it
doesn't. Or do I have to build with a special sanitizer flag?
(5) Your branch does NOT solve the problems in our codes, I do see the same
failures in our test suite like with the gcc trunk/master.
The test-suite for the gcc itself did not work because
of this:
sys/types.h
/usr/local/packages/iains_gcc_git/fixincludes/tests/base/sys/types.h differ:

There were fixinclude test FAILURES
make[2]: *** [check] Error 1
make[1]: *** [check-fixincludes] Error 2
make: *** [do-check] Error 2
Also `make install` did not work properly due to the following error (which is
strange, as make worked without problems).
