GetCapture can reuse the bool pointer argument of GenericCaptureGetter
instead of duplicating that logic with additional checks.
The check also incorrectly checks for undefined while
GenericCaptureGetter returns the empty string on failure.

Now that all accesses to the last match info are in C++ and TF code, we can
finally turn the last match info into a FixedArray. Similar to the ArrayList,
it uses its first field to store its length and grows dynamically in amortized
O(1) time.
Unlike previously, this means that the last match info pointer stored on the
context can actually change (in case the FixedArray needs to grow).

Inspected context is created in V8InspectorImpl::contextCreated method and destroyed in V8InspectorImpl::contextDestroyed.
Both methods takes valid v8::Local<v8::Context> handle to the same context, it means that context is created before InspectedContext constructor and is always destroyed after InspectedContext destructor therefore context weak callback in inspected context should be never called.
It's possible only if inspector client doesn't call contextDestroyed which is considered an error.
Therefore CHECK(false) is added into context weak callback to be sure that v8::Context always survives inspected context.

This ports RegExpInitialize, IsRegExp, InternalMatch and InternalReplace to C++
/ TurboFan. InternalMatch is in TurboFan because it calls RegExpExecStub and
needs to construct a RegExpResult (which are, respectively, a PlatformStub and
a CodeStubAssembler function).
Except for LastMatchInfo (and GetSubstitution, which could be moved to string.js
anytime), regexp.js is now completely empty.

With --trace-ic flag, the function names and the source positions are
not shown for interpreted functions. Interpreted functions have an extra
frame built by bytecode handlers which has to be skipped to get the
interpreted function's frame. Also the code offsets are computed differently
for interpreted functions.

This CL fixes the debugger interface to provide correct (high-level)
information for asm.js frames.
It moves the computation of the source position from the FrameInspector
to the individual StackFrame implementations, such that we can easily
specualize it for certain frame types, and can potentially reuse this
in other locations.
Also, we are finalizing the setup of the wasm module earlier, before
executing the start function. This is required for correct stack traces
during the execution of the start function.

When we inlined a [[Construct]] call to a subclass constructor, we can
also inline the super constructor call (either explicit or implicit),
since we have a concrete JSFunction constant for the subclass and we
can thus constant-fold the %_GetSuperConstructor intrinsic. We don't
need any guards here since the prototype of subclass constructors is
non-writable, non-configurable in ES6.
