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.

Kaelyn Uhrain 980bdb9dfb Expand array bounds checking to work in the presence of unary & and *, 
and to work with pointer arithmetic in addition to array indexing.

The new pointer arithmetic porition of the array bounds checking can be
turned on by -Warray-bounds-pointer-arithmetic (and is off by default).
