Regression: ICE genCheckedRecordField with unsafeAddr and macros

[mratsim]

This is a followup to #23760 that fixed #23755 to try to get Constantine to compile on devel.

Unfortunately there is yet another regression on devel introduced in #23477 related to this when calling bindSym'ed constants (or so i suppose):

func getOne*(T: type FF): T {.noInit, inline.} =
  cast[ptr T](T.getMontyOne().unsafeAddr)[]

The crash is

[...]/t_debug_ice.nim(20, 5) Error: internal error: genCheckedRecordField
No stack traceback available
To create a stacktrace, rerun compilation with './koch temp c <file>', see https://nim-lang.github.io/Nim/intern.html#debugging-the-compiler for details

Full repro, sorry for the length, the bug tends to be finicky and disappears if nudged a bit too much. Also as mentioned in the code comments, everything is already a pile of workarounds for #14021 and #16774
