    This is a reland of e28dadc2
    
    The original failure was due to a stale Win32 bot. The reland failure
    was due to idempotent task deduplication returning the exact same
    failure. See crbug/1196064
    
    Original change's description:
    > [ptr-cage] Rename IsolateRoot to PtrComprCageBase
    >
    > 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.
