Compiling the test case in the patch with -O2 -m32 without the fix,
the program will abort. The problem is a var decl whose address is
taken is not marked as addressable leading to bad SSA update (missing
VUSE). (the triaging used the the .after and .after_cleanup dump diff

The existing push_mult pattern would service thumb1 with just
