[InstCombine] Do not exercise nested max/min pattern on abs
Summary:
This is a fix for assertion failure in
`getInverseMinMaxSelectPattern` when ABS is passed in as a select pattern.
We should not be invoking the simplification rule for
ABS(MIN(~ x,y))) or ABS(MAX(~x,y)) combinations.
Added a test case which would cause an assertion failure without the patch.
