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.

; When %b is 0, %for.body13 is an infite loop. In this case the loaded

|
|
; This is a problem when DeLICM tries to map %1 to %arrayidx16 because
|
|
; %1 has no corresponding when %b == 0 and therefore hat no location
|
|
; where it can be mapped to. However, since %b == 0 results in an
|
|
