      [turbofan] Add backend support for float32 operations. · 8dad78cd
      bmeurer authored
      This adds the basics necessary to support float32 operations in TurboFan.
      The actual functionality required to detect safe float32 operations will
      be added based on this later. Therefore this does not affect production
      code except for some cleanup/refactoring.
      
      In detail, this patchset contains the following features:
      - Add support for float32 operations to arm, arm64, ia32 and x64
        backends.
      - Add float32 machine operators.
      - Add support for float32 constants to simplified lowering.
      - Handle float32 representation for phis in simplified lowering.
      
      In addition, contains the following (related) cleanups:
      - Fix/unify naming of backend instructions.
      - Use AVX comparisons when available.
      - Extend ArchOpcodeField to 9 bits (required for arm64).
      - Refactor some code duplication in instruction selectors.

      Added %_NewConsString intrinsic. · 0a7d4f49

      No compiler support for now (BTW: %_NewString, doesn't have that,
      either), inline allocation will come later. Hopefully the last
      intrisic to add for a StringAddStub POC...
