Alexei Starovoitov 624cd2a176 selftests/bpf: Convert exceptions_assert.c to bpf_cmp
Convert exceptions_assert.c to bpf_cmp_unlikely() macro.

Since

bpf_assert(bpf_cmp_unlikely(var, ==, 100));
other code;

will generate assembly code:

  if r1 == 100 goto L2;
  r0 = 0
  call bpf_throw
L1:
  other code;
  ...

L2: goto L1;

LLVM generates redundant basic block with extra goto. LLVM will be fixed eventually.
Right now it's less efficient than __bpf_assert(var, ==, 100) macro that produces:
  if r1 == 100 goto L1;
  r0 = 0
  call bpf_throw
L1:
  other code;

But extra goto doesn't hurt the verification process.
