[AliasAnalysis] Initialize a member variable that may be used by unit test.
The unit tests in BasicAliasAnalysisTest use the alias analysis API
directly and do not call setAAResults to initalize AAR. This gives a
valgrind error "Conditional Jump depends on unitialized variable".
On most buildbots the variable is nullptr, but in some cases it can be
non nullptr leading to seemingly random failures.
These tests were disabled in r366986. With the initialization they can be
enabled again.
Fixes PR42719
