perf annotate-data: Handle direct global variable access

Like per-cpu base offset array, sometimes it accesses the global
variable directly using the offset.  Allow this type of instructions as
long as it finds a global variable for the address.

  movslq  %edi, %rcx
  mov     -0x7dc94ae0(,%rcx,8), %rcx   <<<--- here

As %rcx has a valid type (i.e. array index) from the first instruction,
it will be checked by the first case in check_matching_type().  But as
it's not a pointer type, the match will fail.  But in this case, it
should check if it accesses the kernel global array variable.
