Add get_unaligned_le16(), get_unaligned_le32 and get_unaligned_le64, same as include/asm-generic/unaligned.h. And add include/asm-generic/unaligned.h to check-headers.sh bringing tools/include/asm-generic/unaligned.h up to date so that the kernel and tools versions match. Use diagnostic pragmas to ignore -Wpacked used by perf build.
