This cl reduces the print of "Call to builtin" which only be printed when call builtin and return to builtin.

Turbolizer can fail to open traces that contain 'StoreLine' nodes.
There is a problem in operator<<(std::ostream& os, StoreLaneParameters
params) that prints StoreLaneParameters.laneidx as a char and not as
an integer, and this can cause the insertion of string terminators in
the trace json file.
This CL fixes the issue.

This CL addresses two problems:
- the previous implementation of the large-function TF bailout
didn't work for streaming compilation, because it tried to look
at the size of wire bytes that weren't yet available. Moving the
logic so it gets executed later ensures that the function size
is available.
- module serialization currently requires all functions to be
compiled with Turbofan, so the hard limit breaks serialization for
modules containing such huge functions. This CL enables the limit
only for --experimental-wasm-gc, so that non-experimental modules
continue to be serializable as they always have been. In the
future, we will avoid this limitation by making serialization more
flexible.

Previously we had passed kOnEntryBreakpointPosition as a marker through
the regular SetBreakPointForScript() logic and handled that specially in
WasmScript, however this instrumentation breakpoint is special and gets
in the way of returning more information about a regular breakpoint in
case of crbug.com/700516, so I decided to just isolate that into it's
own method, especially since the only user already special-cases Wasm
anyways.
