Merge branch 'First set of verifier/*.c migrated to inline assembly'

Eduard Zingerman says:

====================

This is a follow up for RFC [1]. It migrates a first batch of 38
verifier/*.c tests to inline assembly and use of ./test_progs for
actual execution. The migration is done by a python script (see [2]).

Each migrated verifier/xxx.c file is mapped to progs/verifier_xxx.c
plus an entry in the prog_tests/verifier.c. One patch per each file.

A few patches at the beginning of the patch-set extend test_loader
with necessary functionality, mainly:
- support for tests execution in unprivileged mode;
- support for test runs for test programs.

Migrated tests could be selected for execution using the following filter:

  ./test_progs -a verifier_*

An example of the migrated test:

  SEC("xdp")
  __description("XDP pkt read, pkt_data' > pkt_end, corner case, good access")
  __success __retval(0) __flag(BPF_F_ANY_ALIGNMENT)
  __naked void end_corner_case_good_access_1(void)
  {
          asm volatile ("                                 \
          r2 = *(u32*)(r1 + %[xdp_md_data]);              \
          r3 = *(u32*)(r1 + %[xdp_md_data_end]);          \
          r1 = r2;                                        \
          r1 += 8;                                        \
          if r1 > r3 goto l0_%=;                          \
          r0 = *(u64*)(r1 - 8);                           \
  l0_%=:  r0 = 0;                                         \
          exit;                                           \
  "       :
          : __imm_const(xdp_md_data, offsetof(struct xdp_md, data)),
            __imm_const(xdp_md_data_end, offsetof(struct xdp_md, data_end))
          : __clobber_all);
  }

Changes compared to RFC:
- test_loader.c is extended to support test program runs;
- capabilities handling now matches behavior of test_verifier;
- BPF_ST_MEM instructions are automatically replaced by BPF_STX_MEM
  instructions to overcome current clang limitations;
- tests styling updates according to RFC feedback;
- 38 migrated files are included instead of 1.

I used the following means for testing:
- migration tool itself has a set of self-tests;
- migrated tests are passing;
- manually compared each old/new file side-by-side.

While doing side-by-side comparison I've noted a few defects in the
original tests:
- and.c:
  - One of the jump targets is off by one;
  - BPF_ST_MEM wrong OFF/IMM ordering;
- array_access.c:
  - BPF_ST_MEM wrong OFF/IMM ordering;
- value_or_null.c:
  - BPF_ST_MEM wrong OFF/IMM ordering.

These defects would be addressed separately.
