  [Operator] Truncate large type sizes in GEP calculations

If the size is larger than the index width, truncate it instead
of asserting.

Longer-term we should consider rejecting types larger than the
index size in the verifier, though this is probably tricky in
practice (it's address space dependent, and types are owned by
the context, not the module).

Fixes https://github.com/llvm/llvm-project/issues/116960.
