This function is used when an object method needs to be bound to the
receiver to be invoked elsewhere. Using bind() should be more efficient
here than wrapping it in an anonymous function, and it prevents
unexpected call frames from appearing in the stack trace.

This change makes the returned stack traces more similar to what you'd
get in a regular Go runtime. In particular, it skips certain
GopherJS-specific prelude functions like `$callDeferred()`. I expect we
will be adding to the list as we discover other edge cases.

We also rename certain functions to match their upstream counterparts,
since parts of the standard library rely on this. We mark them as
reserved symbols for prelude minification to make sure this doesn't
break when minified.

This prevents pc collision when minified and virtually all calls and
functions are on the same line.

This change resolves `testing.TestTBHelper` test failure in Go 1.18.

 - Avoid use of unsafe in TestNestedMethods and TestEmbeddedMethods.
 - Skip TestNotInHeapDeref and TestMethodCallValueCodePtr, which concern
   low-level GC and heap details, inapplicable to GopherJS.
 - Skip TestIssue50208 until generics are supported.
 - Add a hack into methodNameSkip() to make method names match what the
   tests expect. gopherjs#1085 would
   be a better long-term solution.
 - Stub out verifyNotInHeapPtr(), which is also not applicable to
   GopherJS.
