This patch set extends the eBPF test suite in the test_bpf kernel module
to add more extensive tests of corner cases and new tests for operations
not previously covered.

Changes since v1:
 * Fixed bad jump offset in JMP32 tests that would cause a test
   to pass in some cases when it should fail (1/14).
 * Added comment explaining the purpose of the register clobbering
   test case for ALU operations implemented with function calls (8/14).
 * Fixed bug in test case that would cause it to pass in some cases
   when it should fail (8/14).
 * Added comment explaining the branch conversion test (10/14).
 * Changed wording in commit message regarding 32-bit context
   argument, /should/will/ (11/14).
 * Removed unnecessary conditionals in tail call test setup (14/14).
 * Set offset to 0 when preparing tail call instructions (14/14).
 * Formatting fixes and cleanup in tail call suite (14/14).
