The implementation has been mostly copied from the Go reference
implementation with some small changes to fit TinyGo.

In addition, this commit also contains the following:
- A set of tests copied from the Go reflect package.
- An increased stack size for the riscv-qemu and hifive1-qemu targets
(because they otherwise fail to run the tests). Because these
targets are only used for testing, this seems fine to me.
