c89cfe1e6e peepopt: add shiftpow2 pattern 
Rewrite power-of-two indexed word selects to $bmux when the shift
amount already carries the scale as low zero bits.

Keep the rule to non-overlapping selections and bound the generated
mux ways. Add regressions for aligned shifts, padding, signed
extension, and shiftmul handoff cases.

32f5044eaf Clarify "Not passing module as function argument" comment 
This correct in terms of intent, it's just not fully enforced due to const laundering.

72a21fe01d Introduce RmStats struct to encapsulate removal statistics 
Turns out this is not strictly necessary for this PR but it's
still a good thing to do and makes it clearer that the stats
are not modified in a possibly racy way.
