#5402: Exit code is wrong with dynamically loaded libraries

---------------------------------+------------------------------------------
Here's a simple scenario that goes wrong:
Program starts, calls hs_init(), hs_init_count=1
Program loads some Haskell library that calls hs_init(), hs_init_count=2.
Program does exitWith 99, which calls shutdownHaskellAndExit(99), which
calls hs_exit_(). Since hs_init_count>1 it will do nothing. Control
returns to shutdownHaskellAndExit, since hs_init_count>0 it will do
nothing, i.e., it throws away the exit code 99.
Now real_main() gets control back, and calls shutdownHaskellAndExit(0).
The whole program now exits with code 0, rather than 99.
The solution is probably to track the last non-0 exit code encountered in
shutdownHaskellAndExit and use that as the exit code in real_main().
