Hi,
When testing, I've noticed, that Asan-bootstrapped GCC should be
executed with ASAN_OPTIONS=detect_leaks=0 because of memory leaks in
GCC, reported by Leak Sanitizer.
When I ran Asan test on Asan-bootstrapped GCC, some of them fail with
memory leaks into GCC, even if Lsan is disabled. This caused by slightly
wrong logic in saving/restoring env variables functionality in
gcc-dg.exp (some tests override ASAN_OPTIONS and this env variable isn't
restored correcty).
This tiny patch seems to fix the issue.
Tested on x86_64-pc-linux-gnu.
Ok to commit?
