Previously, DateTimeFormat.prototype.formatToParts returned an object
with the property key 'dayperiod' which is incorrect as per the spec.
This patch updates the property key to say 'dayPeriod', making this spec
compliant.

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.

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 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.
