- introduced __builtin_bpf_passthrough() and use it for user barrier instead of inline asm. I found inline asm has some impact on inlining when running selftests (specifically checked for map_ptr_kern.c).
- introduced an IR pass at the beginning of target dependent optimizations to (1). ensure reloc globals not in PHI node, (2). remove __builtin_bpf_passthrough(). (3). coalescing reloc globals if possible.

This patch can now pass all selftests.
