The previous method was too brittle as applying a variable number of arguments to Date can be manipulated in too many ways, e.g. concat and apply semantics.
The new method shoud suffice for most cases.

Later manipulation of Array.prototype.concat could lead to calling the Date constructor with empty arguments list. This let a non-mocked date slip in.

The old proxy only mocked out constructor calls and didn't intercept function application. It also kept the original constructor property, through which non-mocked dates could be constructed again.

This wraps float arrays with a proxy to make raw buffer use slow paths avoiding different NAN patterns.
This also mocks out large typed arrays when passing the lenth as third constructor parameter.

This disables optimizations when using typed float arrays in
correctness fuzzer test cases. Otherwise, different NaN patterns
in float typed arrays might lead to different observations when
using the buffer in an int array view.

Initial version of the correctness fuzzer harness for manual testing
and experiments.
For automated usage, some outstanding TODOs are left in the code. E.g.
- Hash source file names in error case
- Bundle script in out directory with executables
- Some suppressions are tied to already fixed bugs. We'll keep it like that for now to test
removing those suppressions in production later.
