Revert of [turbofan] Enable super constructor inlining. (patchset #1 id:1 of https://codereview.chromium.org/2409423006/ )

Reason for revert:
As adamk@ pointed out, this is not correct. Some more changes required instead

Original issue's description:

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.

Any context outer to what we're parsing already has proper context allocation, so we don't need to check those scopes.

In a fuzzer testcase I found locally the ast-decoder spent a lot of time
in the decoding of kExprBrTable after the decoder already found an

actually crash. It only run out of memory in the chromium fuzzer.

This moves the implementation of @@replace from regexp.js to builtins-regexp.cc
(the TurboFan fast path) and runtime-regexp.cc (slow path). The fast path
handles all cases in which the regexp itself is an unmodified JSRegExp
instance, the given 'replace' argument is not callable and does not contain any
'$' characters (i.e. we are doing a string replacement).
