Make 'error' include the CCS call stack when profiled
Summary:
The idea here is that this gives a more detailed stack trace in two
cases:
1. With `-prof` and `-fprof-auto`
2. In GHCi (see #11047)
Example, with an error inserted in nofib/shootout/binary-trees:
```
$ ./Main 3
Main: z
CallStack (from ImplicitParams):
error, called at Main.hs:67:29 in main:Main
CallStack (from -prof):
Main.check' (Main.hs:(67,1)-(68,82))
Main.check (Main.hs:63:1-21)
Main.stretch (Main.hs:32:35-57)
Main.main.c (Main.hs:32:9-57)
Main.main (Main.hs:(27,1)-(43,42))
Main.CAF (<entire-module>)
```
This doesn't quite obsolete +RTS -xc, which also attempts to display
more information in the case when the error is in a CAF, but I'm
exploring other solutions to that.
Includes submodule updates.
