      Reland^2 "[ptr-cage] Rename IsolateRoot to PtrComprCageBase" · 627b6b2f
      Shu-yu Guo authored 
      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.

      [wasm-simd] Move some macro-assembler functions to shared · 4b90ad75
      Ng Zhi An authored 
      These functions have the same signature for both SSE and AVX versions.
We move them all into SharedTurboAssembler. Need to fixup a couple of
callsites, since now we use a template helper to call the right
function, whereas previously it was overloaded and there was implicit
conversions from int to uint8_t.
