Correct licensing (#1608) In order to satisfy the project's formatting rules, license information was inserted into a number of files where it had been mistakenly omitted by the original contributors [1]. In many cases, the license information did not accurately describe the contributor or the time of contribution. Update the information according to the information provided by the contributors at the time each file was authored: - atomicsHelper.js - a72ee6d91275aa6524e84a9b7070103411ef2689 - detachArrayBuffer.js - 70c7375be83137015da2c5d6d29a3c40ad3cb5b1 - nans.js - b17ffc029850e3c32d51c68e0281ab7b1a4c193b - nativeFunctionMatcher.js - 6b7cbb50350e478a543da40d02492aa8f45a792d - proxyTrapsHelper.js d530c87b41584d47d95bb78dccf592c9c5c8f7b1 - regexpUtils.js - 44b40e083ec851cd8448d5fe4755bdfc9f0dc14c - tcoHelper.js - 4dc81d37886f49512eb60dafe13b794af5ffeb29 [1] 4ea2931f169d4a4b5a9a4a7c731cc92bf7b3e13c

Update all harness files to pass linting. (#1153) ``` $ python tools/lint/lint.py --whitelist lint.whitelist harness/*.js Linting 25 files. Linting complete. 0 errors found. ``` - Renames detachArrayBuffer-$262.detachArrayBuffer.js -> detachArrayBuffer-host-detachArrayBuffer.js (previous naming prevents command-click from terminal) Signed-off-by: Rick Waldron <waldron.rick@gmail.com>

description: |
A collection of NaN values produced from expressions that have been observed
to create distinct bit representations on various platforms. These provide a
weak basis for assertions regarding the consistent canonicalization of NaN
values in Array buffers.
lint: add rule to verify use of harness files Verify that every test file which references a harness file using the "includes" directive also contains at least one reference to a value defined in the harness file. To support this check, extend each harness file with a list of values which it defines.

Add tests for NaN handling with Typed Arrays (#623) Ensure that NaN values are canonicalized consistently by all invocations of SetValueInBuffer. Also ensure that `%TypedArray%.prototype.set` and `%TypedArray%.prototype.slice` preserve the bit-level encoding of the source data. Use a set of experimentally-derived expressions known to produce NaN values with distinct bit patterns in various platforms.
