When processing imports of an instance, we were storing pointers to
exported (and re-imported) wasm functions in the code table of the
importing module. This is dangerous since imports are instance specific.
Avoid ever storing call targets for imports in the NativeModule.
Instead, read the call targets from the imports table of the instance.

The js-to-wasm wrappers are shared across instances, so we cannot
directly call the instance-specific wasm-to-js wrappers. Instead, we

This was set very regularly in FillFunctionInfo, but it was almost
always set to kNoReason, because the associated SFI had no bailout
reason. Given that having a bailout reason is the rare case, we
just assume an empty bailout reason, and use the rare_data_ struct
to store the string pointer if we do need it.
This saves another pointer of space on the CodeEntry object (approx
1.4 MiB on the node server example).

We need to change WasmExportedFunction to call imported functions via

Currently ProfilerListener holds all the CodeEntries it ever
created during the profiling session. It is not capable of removing
entries corresponding to the code objects discarded by GC as there's
no such code event.
However it is sometimes possible to tell if a code object was GCed.
Hook up to the CodeMap code entry removal and if the entry has never
been hit by a sample we can safely delete it.
As a bonus the CodeEntryInfo size has been reduced on x64, which also
saves 8 x <number of code entries> bytes.

This CL adds support for inlined functions in Turbolizer. It is also a
refactoring of the Turbolizer code-base. Most importantly, handling of
source positions changed to exact source positions, and not code ranges.
This improves selection interoperability between different phase views.
A separate CL changes the Turbolizer JSON format to include inlining
information. This Turbolizer update, however, is intended to be backwards
compatible with the JSON format Turbolizer generated before the JSON
format change.
