Hi,

Here is one more merge of libsanitizer (last one was in Sept).

Tested on x86_64 Ubuntu 14.04 like this:
rm -rf */{*/,}libsanitizer && make -j 50
make -j 40 -C gcc check-g{cc,++}
RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} asan.exp' && \
make -j 40 -C gcc check-g{cc,++}
RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} tsan.exp' && \
make -j 40 -C gcc check
RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} ubsan.exp' && \
echo PASS

Expected ChangeLog entry:
