[Codegen][SelectionDAG] X u% C == 0 fold: non-splat vector improvements

[lebedev.ri]

Summary

Four things here:

1. Generalize the fold to handle non-splat divisors. Reasonably trivial.
2. Unban power-of-two divisors. I don't see any reason why they should be illegal.
   • There is no ban in Hacker's Delight
   • I think the ban came from the same bug that caused the miscompile - in floor((2^W - 1) / D) we were dividing by D0 instead of D, and we were ensuring that D0 is not 1, which made sense.
3. Unban 1 divisors. I no longer believe Hacker's Delight actually says that the fold is invalid for D = 0. Further considerations:
   • We know that
     • (X u% 1) == 0 can be constant-folded to 1,
     • (X u% 1) != 0 can be constant-folded to 0,
   • Also, we know that
     • X u<= -1 can be constant-folded to 1,
     • X u> -1 can be constant-folded to 0,
   • https://godbolt.org/z/7jnZJX https://rise4fun.com/Alive/oF6p
   • We know will end up with the following: (setule/setugt (rotr (mul N, P), K), Q)
   • Therefore, for given new DAG nodes and comparison predicates (ule/ugt), we will still produce the correct answer if: Q is a all-ones constant; and both P and K are *anything* other than undef.
   • The fold will indeed produce Q = all-ones.
4. Try to re-splat the P and K vectors - we don't care about their values for the lines where divisor was 1.

It really bothered me, so here's alive proofs for powers-of-two:

$ ~/src/alive2/build-Clang-release/alive /tmp/test.ll 
OMP: Info #270: omp_set_nested routine deprecated, please use omp_set_max_active_levels instead.
Processing /tmp/test.ll..

----------------------------------------
Name: power-of-two
  %o0 = shl i16 1, %K ; so %o0 is a power-of-two
  %o1 = urem i16 %X, %o0
  %r = icmp eq i16 %o1, 0
=>
  %o0 = shl i16 1, %K ; so %o0 is a power-of-two
  %o1 = urem i16 %X, %o0
  %n0 = mul i16 %X, 1 ; multiplicative inverse of d0=1 is 1
  %n1 = fshr i16 %n0, %n0, %K
  %n2 = udiv i16 -1, %o0
  %r = icmp ule i16 %n1, %n2

Done: 1
Optimization is correct!

This comment doesn't really grok well, if I've understood correctly it should be something like:

"If Values contains values that either match the predicate and the non-matching values are the same 'splat' values, then replace all of them with the 'splat' value."

But I'm not sure that's much better.

Is this code really necessary? Can't you just use SetCC/Select like we do in the BuildDIV methods? SimplifyDemandedBits/SimplifyDemandedVectorElts are more likely to deal with it then.

This is absolutely *NOT* *necessary*.
The fold is still fully correct without this if (HadOneDivisor) block
(and without corresponding if (D.isOneValue()) block).

There is no correctness reason to add any extra nodes if we had 1 divisor,
therefore less nodes == better.

The only thing this does is what it looks like - for the channel where the divisor was 1,
we don't care what multiplier and shift amounts will be, therefore if we can make those
constant vectors a splats, we should be better off that way.

I can totally drop this splatting :)

Err, what i was trying to say was: i certainly did not run ctmark.
I certainly did run test-suite for earlier patches, but i don't recall if i did run it here.

Cheers - instead of adding this to SelectionDAG, please can you just put it TargetLowering.cpp as a static helper for prepareUREMEqFold?

Thanks for taking a look!
Rebased, addressed review notes.

I haven't used find_if_not before - so this is guaranteed to return nullptr for no match?

Whoops, neither llvm wrappers nor the STL versions return nullptr here, this should be checking for != Values.end()
Thanks!

Address review notes.
While turnVectorIntoSplatVector() change is not NFC, i don't believe that issue can be triggered through it's only user.

Better to use "auto SplatValue"? I'd expect the return type to be some kind of iterator type not a regular pointer.
