Add a checker for locator (test is not complete yet).

The logic of finding basic decl in LocatorChecker:

- `int *B; omp target map(*B)`
  - B
    - pointer count (* in type): 1
    - deref count: 1
    - B is basic decl since pointer count equal to deref count
- `int *B, l; omp target map(*(B+l))`
  - B
    - pointer count (* in type): 1
    - deref count: 1
    - B is basic decl since pointer count equal to deref count
  - l
    - pointer count (* in type): 0
    - deref count: 1
    - pointer count = 0, deref count 1 => not equal
- `int **B, **l; omp target map((B+**l)[1][2]`
  - B
    - pointer count (* in type): 2
    - deref count: 2 (2 array subscript)
    - B is basic decl since pointer count equal to deref count
  - l
    - pointer count (* in type): 2
    - deref count: 4 (2 array subscript, 2 unary op)
    - pointer count = 2, deref count 4 => not equal
