[SelectionDAG] Optimize expansion for rotates/funnel shifts.

[efriedma]

Summary

If the type of a funnel shift needs to be expanded, expand it to two funnel shifts instead of regular shifts. For constant shifts, this doesn't make much difference, but for variable shifts it allows a more optimal lowering.

Also use the optimized funnel shift lowering for rotates.

[lebedev.ri]

Are there tests for i128 funnel shifts/rotates?
Presumably those would benefit on x86_64.

This will pass "true" for the third operand, LegalTypes, which I think makes this call getScalarShiftAmountTy. X86 will always return MVT::i8. That won't be large enough for all valid shift amounts if you're splitting a 1024 bit funnel shift.

Address review comments

[efriedma]

Fix RISCV tests.

[RKSimon]

The x86 codegen looks great - although I think we've both added x86 i128 test coverage :)

The PPC codegen has become more branchy - is that a problem?

If you make this condition SETEQ or SETNE depending on whether it's a left or right shift...

4247

... then you can completely common up the two branches of this "if".

[RKSimon]

@efriedma reverse ping - are you still looking at this?

[RKSimon]

@efriedma This might help us with the regressions on D77804, if you are busy, would you mind if I commandeered this and get it finished please?

[efriedma]

Thanks for taking this over. Sorry about delayed response.
