cff4a00d - AMDGPU: Fix runtime unrolling when cascaded GEPs present (#147700)

AMDGPU: Fix runtime unrolling when cascaded GEPs present (#147700) Cascaded GEP (i.e. GEP of GEP) are not handled when determining if it is ok to runtime unroll loops. This change simply uses `getUnderlyingObjects` to look through cascaded GEPs.
