Refine for virtual method check in mangling script
...
We used the flimsy heuristic of a reference from non-executable memory
to try to guess at whether a reference was a vtable, but now we just
check whether it's been named as a vtable.

JSRF evidently has string pooling enabled (i.e. program-wide

well.

Include namespace in symbol table
...
This introduces its own issues, but without namespaces, symbol names end
up repeated and delinking fails. The delinked symbols also end up
without namespaces, introducing yet more problems. This is an
improvement for now, but we'll need proper namespace importing into
Ghidra at some point.

Disable inlining

JSRF appears to have it disabled despite other optimizations. Even if
it was enabled, anyways, we'd still be decompiling the post-inlining
functions and wouldn't want any further inlining to take place (we want
the compiler to compile each function the way we write it).

Correct .data section ranges in delinked objects
...
The change in the previous commit was a silly case of not thinking
things through, not realizing that the .data range moved to Core.obj was
nowhere near the beginning of the section as it should be. g_game has
been moved back into Jet2.obj (time will tell if this is correct) and a
missed data strucure at the beginning of .data (where it ought to be)
now makes up Core.obj's .data portion.
