selftests/bpf: __imm_insn & __imm_const macro for bpf_misc.h
Add two convenience macro for BPF test cases,
allowing the following usage:
#include <linux/filter.h>
...
asm volatile (
...
".8byte %[raw_insn];"
...
"r1 += %[st_foo_offset];"
...
:
: __imm_insn(raw_insn, BPF_RAW_INSN(...)),
__imm_const(st_foo_offset, offsetof(struct st, foo))
: __clobber_all);
