ConvertToCFG: support min/max in loop bounds.
The recently introduced `select` operation enables ConvertToCFG to support
min(max) in loop bounds. Individual min(max) is implemented as
`cmpi "lt"`(`cmpi "gt"`) followed by a `select` between the compared values.
Multiple results of an `affine_apply` operation extracted from the loop bounds
are reduced using min(max) in a sequential manner. While this may decrease the
potential for instruction-level parallelism, it is easier to recognize for the
following passes, in particular for the vectorizer.
