Merge branch 'bpf-map-val-as-key'

Paul Chaignon says:

====================
Currently, helpers that expect ARG_PTR_TO_MAP_KEY and ARG_PTR_TO_MAP_VALUE
can only access stack and packet memory.  This patchset allows these
helpers to directly access map values by passing registers of type
PTR_TO_MAP_VALUE.

The first patch changes the verifier; the second adds new test cases.

The first three versions of this patchset were sent on the iovisor-dev
mailing list only.

Changelogs:
  Changes in v5:
    - Refactor using check_helper_mem_access.
  Changes in v4:
    - Rebase.
  Changes in v3:
    - Bug fixes.
    - Negative test cases.
  Changes in v2:
    - Additional test cases for adjusted maps.
====================
