Create canonical ScopeInfos for the global this binding and empty function in the read only space, rather than creating them during bootstrapping for each native context. This saves some memory, and also means we don't need to access the native context to get the global this binding in when deserializing a scope info, which is important since parsing should be native context independent.

We were only considering eliminating Stores of size Tagged. There doesn't appear to be a reason why. This CL enables store store elimination for all sizes. For example, in pointer compression, it means that Compressed values can be targeted. In 32 bit versions, it means that doubles can now be targeted. This is safe under the assumption that every byte of a JS object is only ever accessed through one offset. For instance, byte 15 of a given object may be accessed using a two-byte read at offset 14, or a four-byte read at offset 12, but never both in the same program.

Port 0aa204fe Original Commit Message: This CL unifies how stack checks are handled in the Turbofan pipeline across architectures, in preparation for properly handling stack overflows caused by deoptimization in follow-up work. It will also open up possibilities to simplify related logic. How this used to work: JSStackCheck was lowered to a UintLessThan with the stack pointer (sp) and stack limit as inputs. On x64 and ia32, this node pattern was later recognized during instruction selection and rewritten to dedicated operators. On other platforms, including arm and arm64, special logic exists to avoid useless register-to-register moves when accessing the sp. This CL introduces a new StackPointerGreaterThan operator, which takes the stack limit as its sole input. This is what JSStackCheck now lowers to. This is threaded through to code generation, where we emit the appropriate code (in the future, we will apply an additional offset to the sp here). In follow-up CLs, we can remove or replace remaining uses of LoadStackPointer in CSA, Wasm, and the interpreter; and then remove the LoadStackPointer operator, related node matchers, related register constraints, and the pseudo-smi stack limit roots.

Now that all uses of LoadStackPointer have been removed, this CL cleans up related code: - Removed LoadStackPointer. - Removed ArchStackPointer. - Removed IA32StackCheck. - Removed X64StackCheck. - Removed StackCheckMatcher. All stack checks now follow a simple path without matchers or special register constraints: they load the limit and pass it to StackPointerGreaterThan, which is finally handled by code generation.

Jakob Gruber authored
Turbofan applies the following optimization to external reference loads on arm64 and x64: if the root-relative offset to an external reference's address is known to be constant (and the root register has been initialized), calculate the external reference as |kRootRegister + <offset>| instead of loading it from the external reference table. There are two main cases to consider: 1. External references to arbitrary addresses in the native address space, e.g. libc_memcpy. These kinds of external references have a fixed address within the same running process, but may (and likely will) change between processes (e.g.: mksnapshot and later chromium), and the root-relative offset is different for each Isolate within the same process. These kinds of external references can be optimized as above when *not* generating code which will later be serialized, and *not* generating isolate-independent code. 2. External references to addresses within the fixed-size region of the Isolate (essentially: within IsolateData). Since these move with the Isolate, their root-relative offset is guaranteed to be constant at all times. The optimization can always be applied to these cases as long as the root register has been initialized. Prior to this CL, we only recognized and optimized for case 1. This CL additionally adds support for 2. An example of improved code generated due to this CL: Before: // r13 is the kRootRegister on x64. // 0x3010 is the root-relative offset to Isolate::context_address. leaq rdx, [r13+0x3010] movq r8, [rdx] After: movq rdx, [r13+0x3010] Bug: v8:9534 Change-Id: Idfcca751e98a56c0e5ead2c701c12a677df75399 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1748727 Commit-Queue: Jakob Gruber <jgruber@chromium.org> Auto-Submit: Jakob Gruber <jgruber@chromium.org> Reviewed-by:
