Manos Koukoutos ae2c0b1dd2 [wasm][turbofan] Annotate nodes with wasm types 
We introduce wasm types to Turbofan. They are represented by a new
subtype of {TypeBase}.
Types are attached to nodes during graph generation, as nodes are
assigned to wasm values. Therefore, phi nodes corresponding to merges
are not typed. Missing types will be computed, and assigned types will
be narrowed as much as possible, in a retyping phase that will be
introduced later.
