David Majnemer 7e21745e22 Sema: Don't diagnose string + int if the int is value dependent 
Don't send a value dependent expression into the expression evaluator,
HandleSizeof would crash.  Making HandleSizeof handle dependent types
would noisily warn about the operation even if everything turns out OK
after instantiation.

This fixes PR21848.

Nico Weber ccec40d9b7 Add -Wstring-plus-int, which warns on "str" + int and int + "str". 
It doesn't warn if the integer is known at compile time and within
the bounds of the string.
