We have almost 200 uses of the "assert" helper functions in noder and
typecheck. Clearly the tiny bit of extra convenience of writing a
one-line assertion rather than an if+panic is helpful, so we might as
well add functions for this to base itself so that it's easier to
write more informative error messages.

For traceback argument printing, we want to print at most 10
words, then print "..." if there are still more args and/or
fields. The current code has off-by-one error that for 11
non-aggregate typed args, it prints the first 10 but without the
"...". Also, for aggregate-typed args, in some cases it may print
an extra "..." when there is actually no more fields.
The problem for this is that visitType return false (meaning not
to continue visiting) if it reaches the limit anywhere during the
recursive visit. It doesn't distinguish whether it has printed
anything for the current arg. If it reaches the limit before it
prints anything, it means that we're visiting the extra arg/field,
so the caller should print "..." and stop. If it prints
something then reaches the limit, however, the caller should keep
going, and only print "..." at the next iteration when there is
actually an extra arg/field. This CL does so.
Fixes#47159.

In CL 326211 a change was made to switch "go.map.zero" symbols from
non-pkg DUPOK symbols to hashed symbols. The intent of this change was
ensure that in cases where there are multiple competing go.map.zero
symbols feeding into a link, the largest map.zero symbol is selected.
The change was buggy, however, and resulted in duplicate symbols in
the final binary (see bug cited below for details). This duplication
was relatively benign for linux/ELF, but causes duplicate definition
errors on Windows.
This patch switches "go.map.zero" symbols back from hashed symbols to
non-pkg DUPOK symbols, and updates the relevant code in the loader to
ensure that we do the right thing when there are multiple competing
DUPOK symbols with different sizes.
Fixes#47185.

Distinguish the gcshape of all top-level instantiated type from normal
concrete types, even if they have the exact same underlying "shape",
because in a function instantiation, any method call on this type arg
will be a generic method call (requiring a dictionary), rather than a
direct method call on the underlying type (no dictionary).
So, we add the instshape prefix to the gcshape name for instantiated
types, and we make it a defined type with that name.
