vld1 was calling set_neon_register with the wrong size for register. We follow the pseudocode implementation in the manual, by splatting the value into a d register, and writing to the list of registers in a loop.

Foozie came up with a mind-boggling example hitting a similarly mind-boggling bug: object construction (JSObject::New) wants to create the constructor's function initial map (JSFunction::GetDerivedMap -> JSFunction::EnsureHasInitialMap). To do so, it calls JSFunction::CalculateExpectedNofProperties. This harmless sounding function triggers compilation of the function. Since we're running with --always-opt, this is an optimizing compilation. Turbofan ends up depending on the function's "prototype" property, for which it wants to create the initial map so that it can install the code dependency. That is, EnsureHasInitialMap is reentered. At this point there is no further compilation attempt because the bytecode now exists. The initial map is created and installed on the function, and TF records the code dependency on that map. When CalculateExpectedNofProperties returns control to the outer EnsureHasInitialMap, yet another initial map is created and set on the function, forgetting the previous one and thus the code dependency. I'm not sure if this bug can only be observed with --always-opt. The fix is general.

This fixes two issues: - labs resetting didn't account bytes as beeing freed; - large object were not accounted. The CL introduces a single bottleneck for labs resetting in ObjectAllocator, which is aware of StatsCollector. This way NormalSpace is treated as a value object and all invariants are maintained by ObjectAllocator (and Sweeper).

Previously, for the various customisation points of String builtins (like String.prototype.replace), we skipped the customisation symbol lookup (like for Symbol.replace) for Smis. But, we do need to do the lookup for Smis in case Number.prototype or Object.prototype have the Symbol. This missing lookup was creating an observable difference between Smis and HeapNumbers.

Prior to this change, uc16 was typedef'd to (unsigned) uint16_t while uc32 was typedef'd to (signed) int32_t. For consistency, and to avoid unexpected behavior around signed/unsigned comparisons, this changes uc32 to the unsigned uint32_t type. As part of this change, old-style error passing (return -1, check for negative return values) was updated to use named error values.

Remove error reporting from parsing::Parse*, since in most cases we didn't actually want them (clear errors afterward), and there was an issue where Compiler::Compile would try to report errors already reported in ParseAny, which ended up triggering unreachable code. As a drive-by, move some one-off parse exception handling in test-parsing into a CHECKED_PARSE_PROGRAM macro which replaces all the "necessarily positive" calls to parsing::ParseProgram.

{PopToRegister} will most likely find that the stack slot is already holding a register (89% of cases on epic). Thus put the fast path for this in the header, so it can be inlined. Also, {GetUnusedRegister} will mostly find an unused register (95% on epic). Hence, make sure that the code for spilling a register is not inlined. Drive-by: Avoid the call to {LoadToRegister} if we already checked before if the slot is holding a register.

The existing {OwnedVector::New} value-initializes all elements, which means zeroing them in case on integral types. In many cases though we know that we will overwrite the content anyway, so the initialization is redundant. In the case of assembly buffers for wasm compilation, this zeroing showed up with several percent of execution times for some benchmarks. Hence this CL introduces a new {OwnedVector::NewForOverwrite} (along the lines of {std::make_unique_for_overwrite}), which only default-initializes the values (meaning no initialization for integral values).
