Leo Li 20fbad9307 [ConstantHoisting] Avoid hoisting constants in GEPs that index into a struct type. 
Summary:
Indices for GEPs that index into a struct type should always be
constants. This added more checks in `collectConstantCandidates:` which make
sure constants for GEP pointer type are not hoisted.
