A large number of libraries seem to use Buffer.alloc(size, 0)
instead of just Buffer.alloc(size).
We don't need to follow the "create unsafe buffer and fill it" path
(i.e. actually allocate and perform fill) in that situation, that is
better handled by Uint8Array constructor.
Buffer.alloc(size) and Buffer.alloc(size, 0) are equivalent, so
use the same code path.
Not performing the zero-fill manually and having the underlying memory
allocator do it for us can improve speed and reduce the memory usage
for situations where Buffer.alloc(size, 0) is used.

- Rename the special ID that can be used to require `NativeModule`

`internalBinding` in the object exported by `NativeModule.require`

2) Improve the performance of all read floating point functions

as UTF-16. Replace the \u2019 with a regular quote character so that
the files they're in can be stored as one-byte strings. The UTF-16

Fix the fast path for `buffer.fill()` with a single-character string.
The fast path only works for strings that are equivalent to a
single-byte buffer, but that condition was not checked properly
for the `utf8` or `utf16le` encodings and is always true for the
`latin1` encoding.
This change fixes these problems.

As per ecma-262 2015's #sec-%typedarray%-buffer-byteoffset-length,
`offset` would be an integer, not a 32 bit unsigned integer. Also,
`length` would be an integer with the maximum value of 2^53 - 1, not a
32 bit unsigned integer.
This would be a problem because, if we create a buffer from an
arraybuffer, from an offset which is greater than 2^32, it would be
actually pointing to a different location in arraybuffer. For example,
if we use 2^40 as offset, then the actual value used will be 0,
because `byteOffset >>>= 0` will convert `byteOffset` to a 32 bit
unsigned int, which is based on 2^32 modulo.
This is a redo, as the ca37fa527f broke
CI.

As shown in https://github.com/nodejs/node/issues/9096, the offset and
end value of the `slice` call are coerced to numbers and then passed to
`FastBuffer`, which internally truncates the mantissa part if the number
is actually a floating point number. This actually affects the new
length of the slice calculation. For example,
> const original = Buffer.from('abcd');
undefined
> original.slice(original.length / 3).toString()
'bc'
This happens because, starting value of the slice is 4 / 3, which is
1.33 (approximately). Now, the length of the slice is calculated as
the difference between the actual length of the buffer and the starting
offset. So, it becomes 2.67 (4 - 1.33). Now, a new `FastBuffer` is
constructed, with the following values as parameters,
1. actual buffer object,
2. starting value, which is 1.33 and
3. the length 2.67.
The underlying C++ code truncates the numbers and they become 1 and 2.
That is why the result is just `bc`.
This patch makes sure that all the offsets are coerced to integers
before any calculations are done.
