Another RiscLua version

Lua 5.40 recently came out of beta, so I have been compiling it with GCC to produce another version of RiscLua. As RiscLua 800 was based on Lua 5.40 (alpha) I am calling the new version RiscLua 801. If anybody has a better nomenclature let me know it. Numbers are now 64-bit, both integers and floats, and use VFP. If anyone desperately wants a soft-float version for the Iyonix, they should get in touch. I have not yet put it on my website because I want to have a thorough clean up of the libraries, the wimp examples and the documentation first. It will keep me busy during lockdown.

There have been some changes:
A new generational mode for garbage collection.
Local variables can now have attributes, <const> for readonly variables and <close>. The value of a local to-be-closed variable is closed when it goes out of scope. There is a __close metamethod to define what this means. File-handles have the usual notion of closure, by default. Closures of to-be-closed local variables take place in the order reverse to their order of declaration.
Coercion between numbers and strings must now be done explicitly with tonumber and tostring.
There are new functions coroutine.close and coroutine.isyieldable.
The debug library has more information about functions.

You can now download RiscLua 801 and its sources from my website.

Just letting you know that people, or at least a person (confirmed) download and use RiscLua
