Nico Hartmann 88eac4b870 [turboshaft] Basic TypedOptimization and new DeadCodeElimination ... This CL introduces typed optimizations for Turboshaft, which replaces all operations that produce a constant output (and don't have side effects) by the corresponding constant. In addition, a new pass for eliminating dead code is introduced that cannot only remove dead operations, but also rewrite branches that are not required into GotoOps. Drive-by: Introduce -0 as a "special value" for Float32Type and Float64Type to fix a few issues where 0 and -0 have been treated as identical.
