Benedikt Meurer 1f1eb625a8 [objects] Change String::length field to uint32_t. 
This changes the Name::hash_field and Symbol::flags to uint32_t as
well, so that both Symbols and Strings consume one fewer word on 64-bit
architectures now. More importantly the access to String::length is
always a 32-bit field load now, even with 31-bit Smis (i.e. on ARM or
on 64-bit with pointer compression), so the access should be faster.
