bpf: add new insns for bswap_to_le and negation
This patch adds new insn, "reg = be16/be32/be64 reg",
for bswap to little endian for big-endian target (bpfeb).
It also adds new insn for negation "reg = -reg".
Currently, for source code, e.g.,
b = -a
LLVM still prefers to generate:
b = 0 - a
But "reg = -reg" format can be used in assembly code.
