ahaas dd51dd926e [wasm] Change the default lowering of stores. ... The int64-lowering only lowered store instructions with a word64 store representation. For all other stores the default lowering applied. The default lowering replaces all input nodes with both their replacement nodes, which can change the number of input nodes of the lowered node. In WebAssembly there exist stores which take an I64 input and store it with a different representation, e.g. I32. In TurboFan this translates to a store node with word32 store representation and a word64 value input. The default lowering replaces the word64 value input to become two word32 value inputs, which makes the number of inputs of the store node invalid. This CL discards the high word replacement of the value input so that the number of input nodes of a store node does not change in the default lowering.
