This adds support to TurboFan's representation selection for the Word64 representation, and makes use of that to handle indices for memory access and allocation instructions (i.e. LoadElement, StoreElement, Allocate, etc.). These instructions had previously used Word32 as representation for the indices / sizes, and then internally converted it to the correct representation (aka Word64 on 64-bit architectures) later on, but that was kind of brittle, and sometimes led to weird generated code. The change thus only adds support to convert integer values in the safe integer range from all kinds of representations to Word64 (on 64-bit architectures). We don't yet handle the opposite direction and none of the representation selection heuristics for the numeric operations were changed so far. This will be done in follow-up CLs. This CL itself is supposed to be neutral wrt. functionality, and only serves as a starting point, and a cleanup for the (weird) implicit Word64 index/size handling.

This truncation doesn't have a proper meaning anyways and has never been used inside the representation selection. For pointer fields we also don't need to pass on a truncation anyways.

Previously the [[ArrayBufferByteLength]] internal field was represented as a boxed number (i.e. either Smi or HeapNumber) in safe integer range. This is the first step to change the representation of all the array buffer and array buffer view length/offset fields to unboxed integers, to eventually support the full range of 4GiB (and potentially even more) for typed arrays and array buffers. This will allow WebAssembly memories with 4GiB to be usable.

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.

This verifies that asm.js over the internal parameter count limit does not crash. The internal limit is 1000 parameters, and the test was using >3000 parameters. Reduce this down to 1005, and also introduce a test which does not dynamically construct the string and eval it, because the construction of this string takes time. Mark the old test as slow in debug mode.
