This adds the next step to freeing code: We free the actual C++ {WasmCode} objects. This will cause UAF if any C++ code uses stale references. The underlying machine code will still not be freed. For simplicity, this CL changes the vector of owned_code to an ordered set, such that lookup and removal is much simpler. The drawback is that insertion is now more expensive.

Pierre Langlois authored
Improve code generation for stores with write barriers slightly by using the assembler's dedicated scratch registers (x16 and x17 on Arm64, ip on Arm) instead of allocating temporaries. To do this, we've done two things: - Use ip as a scratch register when loading page flags. - TurboAssembler::CallRecordWriteStub() now takes the offset of the slot that's written to rather than its address, removing the need to allocate a temporary register for it. In essence, we've gone from: ``` ;; Do the store. stur x19, [x9, #15] ;; Check *destination* object page flags and jump out-of-line. and x4, x9, #0xfffffffffff80000 ldr x4, [x4, #8] tbnz x4, #2, #+0x1e7c | ;; Check *source* object page flags. | `-> and x4, x19, #0xfffffffffff80000 | ldr x4, [xM, #8] |,--- tbz x4, #1, #-0x1e80 | ;; Compute address of slot. | add x5, x9, #0xf (15) | ;; Setup arguments to RecordWrite | stp x2, x3, [sp, #-32]! | stp x4, lr, [sp, #16] | stp x0, x1, [sp, #-16]! | mov x0, x9 ;; Object address in x9 | mov x1, x5 ;; Slot address in x5 | movz x2, #0x0 | movz x3, #0x100000000 | ;; Call RecordWrite | ldr x16, pc+2056 | blr x16 ``` Which allocates x4 and x5 as temporaries. To: ``` stur x19, [x9, #15] and x16, x9, #0xfffffffffff80000 ;; Using x16 instead of allocating x4. ldr x16, [x16, #8] tbnz x16, #2, #+0x1e7c | `-> and x16, x19, #0xfffffffffff80000 | ldr x16, [xM, #8] |,--- tbz x16, #1, #-0x1e80 | stp x2, x3, [sp, #-32]! | stp x4, lr, [sp, #16] | stp x0, x1, [sp, #-16]! | mov x0, x9 ;; Object address still in x9. | add x1, x9, #0xf (15) ;; Compute the slot address directly. | movz x2, #0x0 | movz x3, #0x100000000 | ldr x16, pc+2056 | blr x16 ``` Finally, `RecordWriteField()` does not need an extra scratch register anymore.

The "stress_background_compile" variant runs on all our bots. We combine it with testing wasm code GC (which kind of fits into background compile stressing) to get more coverage for that. Both features are orthogonal, so we can test both at the same time without loosing any coverage.

Port 08756826 Original Commit Message: Port 4b0f9c85 Original Commit Message: Our {Vector} template provides both {start} and {begin} methods. They return exactly the same value. Since the {begin} method is needed for iteration, and is also what standard containers provide, this CL switches all uses of the {start} method to use {begin} instead. Patchset 1 was auto-generated by using this clang AST matcher: callExpr( callee( cxxMethodDecl( hasName("start"), ofClass(hasName("v8::internal::Vector"))) ), argumentCountIs(0)) Patchset 2 was created by running clang-format.

Wasm compilation units got smaller and smaller with recent refactorings (https://crrev.com/c/1587386, https://crrev.com/c/1587387, https://crrev.com/c/1587388, plus previous CLs). They now only store a function index and the requested compilation tier. Hence there is no reason any more to heap-allocate them. This CL changes the compilation unit queues and interfaces to store and pass compilation units by value. Methods that could return an empty {unique_ptr} before are now returning a {base::Optional}.
