Make exprIsConApp_maybe work better for literals strings
There are two things here
* Use exprIsLiteral_maybe to "look through" a variable bound
to a literal string.
* Add CONLIKE to the NOINLINE pragma for unpackCString# and
unpackCStringUtf8#
See Trac #13317, Trac #10844, and
Note [exprIsConApp_maybe on literal strings] in CoreSubst
I did a nofib run and got essentially zero change except for one
2.2% improvement in allocation for 'pretty'.
