I can see only one patch along the dicussion so I will use it, making
changes to follow phase renaming and documentation?
I am covered by FSF agreement too, on the same Intel's list as Ilya.

Great! I'll be back with patch covering all non functional changes.
Will it be OK to have everything in one patch (including current
functional changes) or I should split it?
Let's also rename the file while we are at it. I'd suggest Redundant Extension
Elimination for the name of the pass,

Initial aim of the pass was to remove zero extentions redundant due to

generic approach and seems like a mini-combiner. Pass may combine two
zero extends or combine zero extend with a constant as a special case
but in other
