35150203e3 selftests/bpf: verifier/prevent_map_lookup converted to inline assembly 
Test verifier/prevent_map_lookup automatically converted to use inline assembly.

This was a part of a series [1] but could not be applied becuase
another patch from a series had to be witheld.

4db10a8243 selftests/bpf: verifier/value_ptr_arith converted to inline assembly 
Test verifier/value_ptr_arith automatically converted to use inline assembly.

Test cases "sanitation: alu with different scalars 2" and
"sanitation: alu with different scalars 3" are updated to
avoid -ENOENT as return value, as __retval() annotation
only supports numeric literals.

82887c2568 selftests/bpf: verifier/unpriv converted to inline assembly 
Test verifier/unpriv semi-automatically converted to use inline assembly.

The verifier/unpriv.c had to be split in two parts:
- the bulk of the tests is in the progs/verifier_unpriv.c;
- the single test that needs `struct bpf_perf_event_data`
  definition is in the progs/verifier_unpriv_perf.c.

The tests above can't be in a single file because:
- first requires inclusion of the filter.h header
  (to get access to BPF_ST_MEM macro, inline assembler does
   not support this isntruction);
- the second requires vmlinux.h, which contains definitions
  conflicting with filter.h.

a6fc14dc5e selftests/bpf: verifier/loops1 converted to inline assembly 
Test verifier/loops1 automatically converted to use inline assembly.

There are a few modifications for the converted tests.
"tracepoint" programs do not support test execution, change program
type to "xdp" (which supports test execution) for the following tests
that have __retval tags:
- bounded loop, count to 4
- bonded loop containing forward jump

Also, remove the __retval tag for test:
- bounded loop, count from positive unknown to 4

As it's return value is a random number.

09b501d905 bpf: Remove bpf_kfunc_call_test_kptr_get() test kfunc 
We've managed to improve the UX for kptrs significantly over the last 9
months. All of the prior main use cases, struct bpf_cpumask *, struct
task_struct *, and struct cgroup *, have all been updated to be
synchronized mainly using RCU. In other words, their KF_ACQUIRE kfunc
calls are all KF_RCU, and the pointers themselves are MEM_RCU and can be
accessed in an RCU read region in BPF.

In a follow-on change, we'll be removing the KF_KPTR_GET kfunc flag.
This patch prepares for that by removing the
bpf_kfunc_call_test_kptr_get() kfunc, and all associated selftests.

The two infinite loops in bound check cases added by commit
1a3148fc17 ("selftests/bpf: Check when bounds are not in the 32-bit range")
increased the execution time of test_verifier from about 6 seconds to
about 9 seconds. Rewrite these two infinite loops to finite loops to get
rid of this extra time cost.
