This patch set adds a number of new tests to the test_bpf.ko test suite.
It also corrects a faulty test case for tail call limits that failed
erronously on the x86-64 and i386 JITs. The tests are intended to verify
the correctness of eBPF JITs.

Changes since v3:
* New patch 13 to fix faulty test cases for tail call error paths (13/14).
* Fixed new tail call limit test accordingly (14/14).

Changes since v2:
* Fixed tail call test case to handle the case where a called function is
  outside the 32-bit range of the BPF immediate field. Such calls are
  now omitted in this test. (13/14)
* Fixed typo in commit message. (7/14)
