    [ptr-cage] Rename IsolateRoot to PtrComprCageBase · e28dadc2
    Shu-yu Guo authored
    Currently, IsolateRoot is both the address of the Isolate root and the
    base address of the pointer compression reservation. This CL teases the
    two uses apart by renaming IsolateRoot to PtrComprCageBase.
    
    - In addition to V8_COMPRESS_POINTERS, add a
      V8_COMPRESS_POINTERS_IN_ISOLATE_CAGE (vs SHARED_CAGE).
    
    - Rename GetIsolate* helpers to GetPtrComprCageBase. When
      V8_COMPRESS_POINTERS_IN_ISOLATE_CAGE is true, the helpers remain as
      aliases to GetPtrComprCageBase.
    
    - Rename kPtrComprIsolateRootAlignment to kPtrComprCageBaseAlignment.
