With this CL the AstDecoder produces an error if it encounters a
grow_memory instruction in an asmjs module. Additionally asmjs
instructions are not allowed anymore in wasm modules.

This patch moves the following parsing method to ParserBase:

- ParseSwitchStatement

It also removes ParseCaseClause and merges it with ParseSwitchStatement,
mainly to avoid the complexity of introducing one more abstract typedef
to be shared between parser implementations, but also because the merged
ParseSwitchStatement is now only 59 lines.

Compare the whole word on 64-bit architectures with the kHoleNanInt64 value
since comparing only upper part produces slightly worse code on x64.
Currently TurboFan is not able to fold (array + ((const1 + index*scale) + const))
into single addressing mode: (array + (const + index*scale)).

The logic to test whether we already reached --max_inlining_levels
when inlining into some optimized function only checked specifically
for FrameStateType::kJavaScriptFunction, and thereby didn't properly
account for FrameStateType::kInterpretedFunction, which is what we
see when we come in via the bytecode pipeline.

This CL introduces a ProtectedLoad instruction with is needed for out
of bounds trap handling. ProtectedLoad behaves like a regular load,
but it takes a context and source position parameter as well. These
are used by an out of line code fragment to generate code to throw a
JS exception for an out of bounds memory reference in Wasm.

These changes a cleaned up subset of
https://codereview.chromium.org/2148743004/

The rest of this feature will follow in future CLs. This includes a
table mapping memory instructions to landing pads as well as the
actual signal handler.

This fixes a corner-case where the bytecode was using the <new.target>
register directly without going through the local variable. The value
might be clobbered because the deoptimizer doesn't properly restore the
value. The label will causes bytecode pipeline to be flushed and hence
ensure {BytecodeRegisterOptimizer} doesn't reuse <new.target> anymore.

For call sites where the target is not a known constant, but potentially
a list of known constants (i.e. a Phi with all HeapConstant inputs), we
still record the call site as a potential candidate for inlining.
In case the heuristic picks that candidate for inlining, we
expand the call site to a dispatched call site and invoke the
actual inlining logic for all the nested call sites.

Like Crankshaft, we currently allow up to 4 targets for polymorphic inlining,
although we might want to refine that later.

This approach is different from what Crankshaft does in
that we don't duplicate the evaluation of the parameters per polymorphic
case. Instead we first perform the load of the target (which usually
dispatches based on the receiver map), then we evaluate all the
parameters, and then we dispatch again based on the known targets. This
might generate better or worse code compared to what Crankshaft does,
and for the cases where we generate worse code (i.e. because we have
only trivial parameters or no parameters at all), we might want to
investigate optimizing away the double dispatch in the
future.

This is a work-around as v8_enable_i18n_support=false does
currently not imply icu_use_data_file_flag=false. The
swarming isolator then tries to find the data file also
in builds without ICU.

Making the implication is non-trivial as icu_use_data_file_flag lives
in ICU and v8_enable_i18n_support lives in V8.
