Robert Nystrom 2a1499b04b Fix horrendously bad bit hashing function.

hashBits() is used to generate a hash code from the same 64 bits used
to represent a Wren number as a double. When building a map containing
a large number of integer keys, it's important for this to do a good
job scattering the bits across the 32-bit key space.

Alas, it does not. Worse, the benchmark to test this happens to stop
just before the performance falls off a cliff, so this was easy to
overlook.

This replaces it with the hash function V8 uses, which has much better
performance across the numeric range.

README.md

This contains the automated validation suite for the VM and built-in libraries.

benchmark/ - Performance tests. These aren't strictly pass/fail, but let us compare performance both against other languages and against previous builds of Wren itself.
core/ - Tests for the built in core library, mainly methods on the core classes. If a bug is in wren_core.c or wren_value.c, it will most likely break one of these tests.
language/ - Tests of the language itself, its grammar and runtime semantics. If a bug is in wren_compiler.c or wren_vm.c, it will most likely break one of these tests. This includes tests for the syntax for the literal forms of the core classes.
limit/ - Tests for various hardcoded limits. The language doesn't officially specify these limits, but the Wren implementation has them. These tests ensure that limit behavior is well-defined and tested.
