Subject: bpf, tests: Add more BPF_LSH/RSH/ARSH tests for ALU64
Patch-mainline: v5.15-rc1
Git-commit: 3b9890ef80f4285d32f2274d20db108e064e5e9e
References: jsc#PED-1377

This patch adds a number of tests for BPF_LSH, BPF_RSH amd BPF_ARSH
ALU64 operations with values that may trigger different JIT code paths.
Mainly testing 32-bit JITs that implement ALU64 operations with two
32-bit CPU registers per operand.
