Hi,

finally, after many distractions, v2 of this series.

Main changes from v1:
 - Restrict to types/modes with padding thanks to Richi's suggestion.
 - Return an array of supported else values and let the vectorizer choose.
 - Undefined else value for GCN.

Bootstrapped and regtested on Power10, x86 and aarch64.
Regtested on rv64gcv.

Testing on GCN would be much appreciated.

Robin Dapp (8):
  docs: Document maskload else operand and behavior.
  ifn: Add else-operand handling.
  tree-ifcvt: Enforce zero else value after maskload.
  vect: Add maskload else value support.
  aarch64: Add masked-load else operands.
  gcn: Add else operand to masked loads.
  i386: Add else operand to masked loads.
  RISC-V: Add else operand to masked loads [PR115336].
