[Liftoff] Fix corner case of register moves If we have both f32 and f64 locals, we use the same register to hold their zero value. On stack transfers, we might thus encounter the same fp register with both the f32 and f64 type. Explicitly allow that case to happen.

[wasm] Rename {Get,Set,Tee}Local to Local{Get,Set,Tee} This brings our constants back in line with the changed spec text. We already use kExprTableGet and kExprTableSet, but for locals and globals we still use the old wording. This renaming is mostly mechanical. PS1 was created using: ag -l 'kExpr(Get|Set|Tee)Local' src test | \ xargs -L1 sed -E 's/kExpr(Get|Set|Tee)Local\b/kExprLocal\1/g' -i PS2 contains manual fixes.
