The `opt -analyze` option only works with the legacy pass manager and might be removed in the future, as explained in llvm.org/PR53733. This patch introduced -polly-print-* passes that print what the pass would print with the `-analyze` option and replaces all uses of `-analyze` in the regression tests.
There are two exceptions: `CodeGen\single_loop_param_less_equal.ll` and `CodeGen\loop_with_condition_nested.ll` use `-analyze on the `-loops` pass which is not part of Polly.

After zero-extend operations and unsigned comparisons we now allow
unsigned divisions. The handling is basically the same as for signed
division, except the interpretation of the operands. As the divisor
has to be constant in both cases we can simply interpret it as an
unsigned value without additional complexity in the representation.
For the dividend we could choose from the different representation
schemes introduced for zero-extend operations but for now we will
simply use an assumption.
