This is a reland of a16add80. The fixes are adding disassembly for pcmpgtq and vpcmpgtq. While fixing also noticed a mistake in assembler for pcmpgtq, which flipped dst and src. Also realized that we don't detect SSE4.2, so adding that in. PS2 contains these changes.

As outlined in the design document linked below, we're removing the support for the non-standard Function.displayName property for the purpose of Error.stack and DevTools Inspector stack traces. The motivation here is that the negative lookup is costly, and we have Function.name as a standard alternative (configurable since ES6 for exactly this reason). I dediced to go with JSFunction::GetDebugName(), since JSFunction::GetName() was confusing in that it'd only get the "name" property's value if it's a data property, but not with accessors. JSFunction::GetDebugName() makes it clear that this is really a debug helper function and might not give you the "name" property value.

This CL adds support for instrumentation breakpoints in wasm. The request for "break on entry" is set on the script, and we need to keep it stored there because there might not be any instances of that wasm module yet. Once instances get created, the flag value is transferred to all instances. The flag stored there is then checked in the function prologue in Liftoff debugging code. This ensures that we will stop at the first valid break position in any function within that module. Hitting that instrumentation breakpoint will then clear the flag from the script and from all other live instances (in the same isolate). A first basic test is contained in this CL. More tests will be added later.

Currently we sometimes refer to baseline code or the baseline compiler by its codename (Sparkplug). The codename is fun, but we should be consistent and call things by one name or the other. Following the pattern of Ignition stuff being called "interpreter", we call Sparkplug "baseline", and leave the codename only in flags and variants.

Following up on https://crrev.com/c/2689185, this CL significantly simplifies the whole implementation of the stack trace capturing. Before this CL, capturing any stack trace (for the purpose of the API or Error.stack) would roughly work like this: 1. The CaptureStackTrace() function uses the StackFrameIterator to walk the system stack. For each native frame it uses the FrameSummary abstraction to get all (including potentially inlined) frames. For each of those it appends a record consisting of six elements to a FrameArray (this holds pointers to the actual closures and receivers). 2. Afterwards the FrameArray is shrinked to the required size, and a new FixedArray is allocated, and initialized with new StackTraceFrame objects where each holds a reference to the FrameArray, the index of the frame, and an initially uninitialized StackFrameInfo reference. This new FixedArray is then returned from CaptureStackTrace() and either stored on a message object or provided to the API as v8::StackTrace. The new approach removes a lot of the machinery in between and directly creates a FixedArray of StackFrameInfo objects in CaptureStackTrace(). These StackFrameInfo objects are directly exposed as v8::StackFrame on the public API, and they hold the six fields that were previously stored flat in the FrameArray. This not only avoids a lot of copying around of data and creation of temporary objects and handles, but most importantly unifies and simplifies the stack frame function inside StackFrameInfo, so you no longer need to wonder which function / object might be responsible for a certain API. There's still a lot of room for improvement. In particular we currently don't cache the source position for a given StackFrameInfo (or globally), but rather recompute it every time. This is still very fast, significantly faster than the previous approach. There are some notable (potentially user visible) changes: - The CallSite#GetPosition() method now consistently returns the Wasm module relative bytecode offset for all Wasm frames (previously it'd return the function relative bytecode offset for non-asm.js Wasm frames). - The column and line numbers returned from StackFrameInfo methods are consistently 1-based now, instead of sometimes being 0-based (Wasm) and sometimes being 1-based (JS and asm.js Wasm). The only potentially noticable difference is that for CallSite#GetLineNumber() no longer returns 0 for Wasm frames, but that was wrong and useless anyways. - CallSite#GetThis() would sometimes return the_hole, another bug flushed out by this CL. The CL also contains some other not noteworthy drive-by-cleanups.
