selftests/bpf: Add verifier tests for xor operation ...
Added some test_verifier bounds check test cases for
xor operations.
$ ./test_verifier
...
#78/u bounds check for reg = 0, reg xor 1 OK
#78/p bounds check for reg = 0, reg xor 1 OK
#79/u bounds check for reg32 = 0, reg32 xor 1 OK
#79/p bounds check for reg32 = 0, reg32 xor 1 OK
#80/u bounds check for reg = 2, reg xor 3 OK
#80/p bounds check for reg = 2, reg xor 3 OK
#81/u bounds check for reg = any, reg xor 3 OK
#81/p bounds check for reg = any, reg xor 3 OK
#82/u bounds check for reg32 = any, reg32 xor 3 OK
#82/p bounds check for reg32 = any, reg32 xor 3 OK
