      [arm] Correctly push and pop double registers on deopt entry · 59a629b5
      Jakob Gruber authored
      The number of available double registers depends on supported CPU
      features on arm. Any code that applies to all double regs must be
      extra-careful to correctly handle either 16 or 32 registers.
      
      This was not the case for deopt entries, which were recently moved
      from a runtime-generated code stub to a mksnapshot-time-generated
      builtin.
      
      This CL fixes the issue by inspecting the runtime value of cpu
      features and acting on it.
