This CL implements load_extend with 2 lanes and all load_splat operations on IA32. The necessary assemblers together with their corresponding disassemblers and tests are also added in this CL. The newly added opcodes include: S8x16LoadSplat, S16x8LoadSplat, S32x4LoadSplat, S64x2LoadSplat, I64x2Load32x2S, I64x2Load32x2U.

This change moves the definitions of the bitfield flags used by Symbol and Map to Torque. Symbol could directly follow the pattern established by SharedFunctionInfo, but Map required some other changes: - Until now, Torque bitfield definitions have required unsigned types. I thought that this would be the least-surprising behavior, since we never sign-extend when decoding bitfield values. However, I believe that the amount of churn involved in making ElementsKind be unsigned outweighs the benefit we were getting from this restriction (and similar difficulties are likely to arise in converting other bitfield structs to Torque), so this CL updates Torque to allow signed bitfield values. - If we try to make Map extend from all of the generated classes that define its flags, we end up with class sizing problems because some compilers only apply empty base class optimization to the first in a row of empty base classes. We could work around this issue by generating macros instead of classes, but I took this as an opportunity for a minor clean-up instead: rather than having bitfield definitions for several different bitfield structs all jumbled together in Map, they can be split up. I think this makes the code a little easier to follow, but if others disagree I'm happy to implement macro generation instead.

This code pattern was then later copied for other instructions too (https://crrev.com/1424333002). The reason for the xorpd is not mentioned in the code though, and I found no other compiler doing this. So maybe it's obsolete by now, and only increases code size.

This removes the support to emit runtime calls in Liftoff code and uses WebAssembly runtime stubs instead. Calls to such stubs are smaller and more efficient. They also use embedded builtins directly instead of the on-heap {Code} object trampolines. This also removes the last use of a runtime call that passes a dynamically loaded CEntry builtin from the macro assembler.

The {shrd} instruction was implemented with switched {src} and {dst} registers. The only users ({ShrPair} and {SarPair}) "fixed" this by passing switched registers again. This CL cleans this up, and adds some DCHECKs that are required for the logic in the pair-wise shifts to work correctly. Also, avoid an unneccessary shift by 0 on ia32.

Reland of https://chromium-review.googlesource.com/c/v8/v8/+/1795358. [builtins] Move non-JS linkage builtins code objects into RO_SPACE Creates an allow-list of builtins that can still go in code_space including all TFJ builtins and a small manual list that should be pared down in the future. For builtins that go in RO_SPACE a Code object is created that contains an immediate trap instruction. Generally these Code objects are still no smaller than CODE_SPACE Code objects because of the Code object alignment requirements. This will hopefully be addressed in a follow-up CL either by relaxing them or removing the instruction stream completely. In the snapshot, this reduces code_space from ~152k to ~40k (-112k) and increases by the same amount.

The {TurboAssembler} already has logic to use the {lzcnt} and {tzcnt} instructions if available, and otherwise falls back to a slightly optimized variant of the previous code. Thus, we just call these methods. Drive-by: Use {movl} instead of {Set} for constant values, for consistency, readability and performance.

CallDebugOnFunctionCall was always using Registers and not Immediates. Then ParameterCount is not really needed. Since updating that, we could update other functions, e.g InvokeFunction, to only use registers too. Also removed now irrelevant variables, e.g definitely_mismatches.

If we do the check in InvokeFunctionCode instead of doing it in CheckDebugHook (now aptly named 'DebugHook'), we can defer the debug hook to the end of InvokeFunctionCode and is to make the common case stay in straight-line code.

The code fields in a JSRegExp object now either contain irregexp compiled code or a trampoline to the interpreter. This way the code can be executed without explicitly checking if the regexp shall be interpreted or executed natively. In case of interpreted regexp the generated bytecode is now stored in its own fields instead of the code fields for Latin1 and UC16 respectively. The signatures of the jitted irregexp match and the regexp interpreter have been equalized.

Stack limits were additionally maintained in pseudo-smi roots. "Pseudo", because we stored the raw limit pointers there, just making sure their values looked like smis by masking the least significant bits. This mechanism is no longer needed now that we can access the stack limit external references as efficiently as the smi 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.

This changes Generate_ContinueToBuiltinHelper to generate code to load the builtin address directly from the builtins table rather than going via the executable code in the trampoline's code object. The set up for Generate_ContinueToBuiltinHelper is changed so that the builtin index is stored on the stack in place of the builtin Code object which is no longer needed.
