BPF programs are normally handled by a BPF interpreter, add BPF JIT
support for LoongArch to allow the kernel to generate native code when
a program is loaded into the kernel. This will significantly speed-up
processing of BPF programs.

The perf events infrastructure of LoongArch is very similar to old MIPS-
based Loongson, so most of the codes are derived from MIPS.

Add system call support and related uaccess.h for LoongArch.
Q: Why keep _ARCH_WANT_SYS_CLONE definition while there is clone3:
A: The latest glibc release has some basic support for clone3 but it is
not complete. E.g., pthread_create() and spawni() have converted to
use clone3 but fork() will still use clone. Moreover, some seccomp
related applications can still not work perfectly with clone3. E.g.,
Chromium sandbox cannot work at all and there is no solution for it,
which is more terrible than the fork() story [1].
