Fix PR2369 by making scalarrepl more careful about promoting

on the number of registers introduced, defaulting to 128/4=32.

"this patch adds code generation hooks for Objective-C constant strings. It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet."
