Michael Zolotukhin 93a3ca7cde [SLPVectorizer] Handle GEP with differing constant index types 
Summary:
This fixes PR27617.

Bug description: The SLPVectorizer asserts on encountering GEPs with different index types, such as i8 and i64.

The patch includes a simple relaxation of the assert to allow constants being of different types, along with a regression test that will provoke the unrelaxed assert.
