  testsuite: fix bytecodeIPE test under +ipe flavours
  
  This patch fixes the bytecodeIPE test under +ipe flavours. It used to
  fail under +ipe because the RTS is built with IPE info, then
  stg_AP_info in RTS carries IPE info, so whereFrom wouldn't return
  Nothing. Now the test checks IPE info of a datacon in the ghci-loaded
  module which is not affected by whether the RTS is built with IPE info
  or not. Fixes #27498.

Changes:

 import Data.Maybe (isJust)

 import GHC.InfoProv (whereFrom)

-marker :: String

-marker = id "bytecode-stub-init"

-{-# NOINLINE marker #-}

+data Marker = Marker

 -- `whereFrom` only succeeds if the module's IPE initializer ran.

 probe :: IO Bool

-probe = isJust <$> whereFrom marker

+probe = isJust <$> whereFrom Marker
