This change makes full 8 GiB guard regions always enabled on 64-bit platforms. Additionally, since all Wasm memory allocation paths have some form of guard regions, this removes and simplifies most of the logic around whether to enable guard regions. This is a reland of https://crrev.com/c/985142. Bug: v8:7619 Change-Id: I8bf1f86d6f89fd0bb2144431c7628f15a6b00ba0 Reviewed-on: https://chromium-review.googlesource.com/996466Reviewed-by:

The AssembleMove and AssembleSwap tests would only perform moves on stack parameters. This limits us to testing with slots that are likely to be in range of loads and stores. As well as only testing memory accesses with positive offsets relative to the frame pointer. This patch addresses these limitations by moving half of the stack parameters into spill slots, to then perform moves on them. Additionally, to increase ranges, we create articial space between each spilled slot. As a drive-by, allow giving custom names to code objects created with the CodeAssemblerTester. It helps a lot inspecting disassembly. And finally, this CL uncovered a bug where I had forgotten to initialize FixedArrays, which would make the incremental marker crash.

Fixes a crash that happens when calling postMessage on an empty typed array. GetBuffer should only call MaterializeArrayBuffer for on-heap buffers, but the on-heap check is slightly wrong. This CL moves the on-heap check logic to the JSTypedArray class so that other parts of the codebase don't need to worry about how that is determined. Also add some dchecks to materialize itself. It should only receive on-heap buffers and should always transform them to off-heap buffers. There is also no reason for it to be static, so change that here too.

In order to clarify the difference between, e.g., InstructionStart and instruction_start, rename as follows: Code::instruction_start -> raw_instruction_start Code::instruction_end -> raw_instruction_end Code::instruction_size -> raw_instruction_size The difference between the camel-case and raw_* function families is in how they handle off-heap-trampoline Code objects. For example, when called on an off-heap-trampoline: raw_instruction_start returns the trampoline's entry point, while InstructionStart returns the off-heap code's entry point (located in the .text section of the binary). Some callsites were updated to call the camel-case function family as appropriate.

This pattern seems to reoccur in the code: Handle<TransitionArray> array = TransitionArray::Allocate(...); <something that causes allocation> // Fill up the array array->set(...); If the allocation causes GC, we try to iterate the TransitionArrray in MarkCompactCollector::ClearFullMapTransitions, and that crashes because it expects the TransitionArray to contain handlers (not undefined). This bug is present e.g., in TransitionAccessor::EnsureHasFullTransition.

test-heap/TransitionsArraySimpleToFull was relying on an allocation happening (and GC being triggered) right at the start of TransitionsAccessor::Insert. That allocation would put the TransitionsAccessor back to the kUninitialized state. If there's no allocation at that point of the program logic, the test will fail, since the TransitionsAccessor will be go to the kFullTransitionArray state. (Needed for the in-place weak ref work, which will remove the allocation at that point.)
