Embarrassingly, while integrating VerifyRegExpSyntax into SpiderMonkey, I realized that I had refactored away the RegExpCompileData* argument, which is necessary for emitting error messages when parsing fails.

The interpreter is missing a static cast when extracting lanes smaller than int32_t and doing an unsigned extend. The array in Simd128 is signed, so a direct cast to uint32_t will be a signed extension. The fix is to, in the unsigned case, cast to unsigned (of the appropriate size) first, then cast to uint32_t.

Display register allocation live ranges alongside sequences in turbolizer. The existing --trace-turbo flag now also outputs the register allocation data as part of the json file alongside the instruction sequence data that is already produced before and after register allocation is performed. This data includes live range intervals for each virtual and fixed register and the state of their assignments. This json data can now be displayed in turbolizer alongside the instruction sequences. The information is presented as a grid, with each grid cell representing a LifeTimePosition of a certain virtual register, determined by the column and row indices respectively. Each LifeTimePosition is shown to be part of an instruction id which itself is shown to be part of a block id. Each interval is shown as a coloured rectangle positioned over the relevant cells, and displaying text to indicate the state of their assignment. The Resizer object has been extended to allow the grid's html panel to be varied in size in the same manner that the left and right panels can be. The size of the grid itself must also be adjusted whenever the div container changes size. The RangeView class is introduced and is created and held by the single SequenceView object used to display the InstructionSequence data before and after register allocation. A checkbox allows the user to show/hide the range view, this is disabled when register allocation data is not provided or more than 249 instructions are in the sequence. The latter being required due to the css grid-row-col limit of 1000 alond with helping alleviate performance issues. The SequenceView object tracks the phase index currently selected as well as whether or not it is currently being shown. This ensures that the RangeView is not hidden and shown when switching between before and after register allocation, allowing for a smoother transition between the two. The scroll position is also saved and restored for convenience. The data about the instruction sequence required for the display is held by the RangeView object and reset whenever a new instruction sequence is shown. The grid div must sync its scroll with the headers and row labels so as to ensure a consistent view. The register allocation data is extracted from the json, with each register row showing all intervals within the relevant ranges. When the view is switched between before and after register allocation, the relevant intervals are swapped in.

This CL brings unary op assembler structure closer to that of binary ops assemblers: - Decrement, Increment, Negate call into UnaryOpWithFeedback, - which takes lambdas specifying smi, float, and bigint logic. - BitwiseNot is different in that it still dispatches using TaggedToWOrd32OrBigIntWithFeedback. - These methods are all implemented in the (hidden) UnaryOpAssemblerImpl class. - The header only exposes UnaryOpAssembler with the bare minimum of API. The last point is the remaining major divergence from binary op assemblers. I just like how this avoids useless implementation details in the header.

Previously both the length and the endColumn for Wasm scripts were reported as 0, and that was sort of okayish, since the front-end was ignoring both of these fields in case of Wasm, and was applying special cases. But these special casing lead to some subtle bugs, and this is the first step towards a more uniform treatment. Source positions for Wasm are in terms of the bytecode, and the column field contains the bytecode offset here, while the line number field is always 0. Hence we send 0 for both startLine and endLine as before, but endColumn now corresponds to the bytecode size.

To ensure that regexp syntax errors are reported as early errors, SpiderMonkey calls ParseRegExp at parse time to validate that the regexp parses properly. This does not require the allocation of named capture information. We have a project underway to completely eliminate the allocation of GC things at parse time, which will require us to suppress the allocation of named capture information (or else jump through hoops to implement FixedArray as a non-GC thing). We can work around this in our shim layer -- for example, by setting a flag on the Factory shim that causes us to allocate dummy objects -- but it's much simpler to add an option to ParseRegExp. (Note: V8 currently does not treat regexp syntax errors as early errors. See https://bugs.chromium.org/p/v8/issues/detail?id=896.)
