JIT: Windows not supported

[joncinque]

The JIT only supports non-Windows targets:

rbpf/src/jit.rs

Lines 934 to 937 in c3dd337

	#[cfg(target_os = "windows")]
	{
	panic!("JIT not supported on windows");
	}

This issue is not pressing, nor is it a call to action. Instead, it can be used for tracking in other systems that may be blocked. I imagine a Windows-JIT will be difficult to implement because of all the POSIX-specific parts of the implementation, and yield very little reward.

It is not so much POSIX, as the only thing POSIX we are using is mmap / mprotect and there should be replacements for that on windows: https://docs.microsoft.com/en-us/windows/win32/api/memoryapi/

The way bigger problem is that windows does not use the System V ABI like everybody else does. So all the x86 registers and the call stack work differently.
