Florian Hahn 8098f2577e [LV] Use Legal::isUniform to detect uniform pointers. ...

Update collectLoopUniforms to identify uniform pointers using
Legal::isUniform. This is more powerful and  brings pointer
classification here in sync with setCostBasedWideningDecision
which uses isUniformMemOp. The existing mis-match in reasoning
can causes crashes due to D134460, which is fixed by this patch.

Fixes https://github.com/llvm/llvm-project/issues/60831.
