perf tools: Add union u64_swap type for swapping u64 data

The following union:
  union {
        u64 val64;
        u32 val32[2];
  } u;

is used on more than one place in perf code and will be used more in
upcomming patches.

Adding union u64_swap to have it defined globaly so we dont need to
redefine it all the time.
