[Bug tree-optimization/32328] [4.2/4.3 Regression] -fstrict-aliasing causes skipped code

trunk has the same problem, but different constraints:

Constraints:

ANYTHING = &ANYTHING
READONLY = &ANYTHING
INTEGER = &ANYTHING
barptr = &bar1
barptr.0_1 = barptr

Points-to sets

NULL = { }
ANYTHING = { ANYTHING }
READONLY = { ANYTHING }
INTEGER = { ANYTHING }
barptr = { bar1 }
bar1 = { }
barptr.0_1 = same as barptr
