Use a growable array instead of an environment during SSA.

Using an environment was convenient because it contains
a growable array. But there's no need for the environment
abstraction when being used as a temporary holder for values
of locals.

   // Copy from `env`. If it's a loop phi for `loop_header`, copy the first
   // input to the loop phi instead. This is for inserting instructions that
   // require an environment (like HDeoptimization) in the loop pre-header.
