The name dictionary allocated to store named captures on the regexp
result object could be too large for regular heap spaces and
ConstructNewResultFromMatchInfo must thus also handle the large object
case.

In the rare case that a tagged template is not initialized before
optimization time, we currently cache this created template in the
feedback vector. If we stop doing this, we simplify the interface
usefully for concurrent compilation and pay little for it.

EscapeRegExpPattern should return a string representation of a
RegExp instance that in turn can be used to construct a new
RegExp instance with the same internal state as the original one.
Previous versions incorrectly escaped '/' also inside character classes
(e.g. /[/]/ returned "[\/]").
This patch properly escapes '/' when necessary and omits unnecessary
escapes.

The client API provides a much simpler interface so that we don't have
to deal with producers, consumers etc. directly. This CL removes all the
code that dealt with the more complex API used previously.
The architecture used here requires that the embedder call into
Tracing::Initialize() to set up the tracing backend. The tracing
controller then connects to this backend when calling
DataSource::Register() and Tracing::NewTrace(). This will ultimately
avoid the need for a virtual call (or two) for every trace event that
need to be dispatched over the API - chrome can provide a backend
and V8 will connect to it opaquely with the same code when tracing is
enabled.

This CL teaches the deoptimizer about JavaScriptBuiltinContinuation
frames that are not preceded by argument adapter frames. This pattern
is used when calling C++ API functions from TurboFan.
This CL fixes a crash when the deoptimizer encounters the pattern
described above. The crash was caused when the deoptimizer tried to
read the arguments of the continuation frame. As no adapter frame
was present, the argument count was read from the SharedFunctionInfo
which had the kDontAdaptArgumentsSentinel value. This translated to
an argument count of ~65000 later down the line, which caused a
FATAL error when the deoptimizer tried to re-construct ~65000
non-existent values.

This CL moves the code responsible for serializing a stack trace frame into
a string, out of messages.cc and into stack-frame-info.cc. Instead of
symbolizing the stack trace frame while serializing, the code is changed to
work on top of StackTraceFrame and StackFrameInfo objects.
The result is that the serialization code no longer cares when a stack trace
frame is symbolized. Symbolization could happen eagerly during capturing, or
lazily the first time any of StackFrameInfo fields are accessed.
Drive-by: Existing users of StackFrameBase::ToString are adapted to the
new SerializeStackTraceFrame API. This includes Isolate::PrintCurrentStackTrace,
which is changed to re-use the existing capturing and serializing mechanism.

This is the combined second and third step of refactoring indirect
function calls through tables with index > 0 to work without runtime
calls.
The first CL introduces the WasmIndirectFunctionTable heap object. For
a table of type anyfunc within a WebAssembly instance,
WasmIndirectFunctionTable stores the size, the signature id's, the
call targets, and the reference parameters for that table. I used the
names that are already used for the matching fields of the
WasmInstanceObject.
The second CL expands the IndirectFunctionTableEntry to work also on
WasmIndirectFunctionTable objects. All changes to a function table go
through this class.
The third CL introduces uses of the WasmIndirectFunctionTable. In this
CL I change the code generation in TurboFan to replace runime calls with
direct accesses to the new WasmIndirectFunctionTable. Additionally I
extended the initialization of WasmIndirectFunctionTable, and also
implement Table.grow.

This assertion was borked, as it accepted obviously "same" values like
the same object. This fixes the predicate by switching both assertSame
and assertNotSame to use {Object.is} underneath. It also adds a new
respective regression test (gotta test the tester).

Large regexp results may exceed kMaxRegularHeapObjectSize and must
thus be allocated in large object space.

Before running OOM on a wasm memory allocation, we trigger a GC, but
only in the isolate which allocates the new wasm memory. Hence if
multiple isolates are involved, we can run OOM anyway. This is a rare
case which did not cause trouble yet in the wild, so skip that test on
the 'isolates' bot for now.

This add signature checking when a constructed {WebAssembly.Function} is

importing itself is not yet implemented and will be done as a follow-up.
