[BPF] Generate BTF DebugInfo under BPF target
This patch implements BTF (BPF Type Format).
The BTF is the debug info format for BPF, introduced
in the below linux patch:
69b693f0ae (diff-06fb1c8825f653d7e539058b72c83332)
and further extended several times, e.g.,
https://www.spinics.net/lists/netdev/msg534640.html
https://www.spinics.net/lists/netdev/msg538464.html
https://www.spinics.net/lists/netdev/msg540246.html
The main advantage of implementing in LLVM is:
. better integration/deployment as no extra tools are needed.
. bpf JIT based compilation (like bcc, bpftrace, etc.) can get
BTF without much extra effort.
. BTF line_info needs selective source codes, which can be
easily retrieved when inside the compiler.
This patch implemented BTF generation by registering a BPF
specific DebugHandler in BPFAsmPrinter.
