We should backport gcc 4.4 regression testcases to gcc 4.3 branch

[H.J. Lu]

Hi,

This 4.3 regression:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38905

is caused by a backport, which also introduced a 4.3
regression:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36765

Since we didn't backport testcases to 4.3 branch, we
didn't notice 4.3 regression when the packport was
applied to 4.3 branch. If we will backport bug fixes
to 4.3 branch, shouldn't we always backport testcases
for all 4.4 regressions?
