This is needed for cases when the memory access is not as big as the width of the data type. For instance, storing i1 (1 bit) would be done in a byte (8 bits). Using 'BitSize >> 3' (or '/ 8') would e.g. give the memory access of an i1 a size of 0, which for instance makes alias analysis return NoAlias even when it shouldn't. There are no tests as this was done as a follow-up to the bugfix for the case where this was discovered (r318824). This handles more similar cases.
