Kelvin Li ef57943e3f [OPENMP] parsing and sema support for 'close' map-type-modifier

prefer that the variables are mapped using a copy into faster 
memory.

Kelvin Li ad9ecbab42 [OpenMP] Allow negative lower bound in array sections based on pointers
OpenMP 4.5 removed the restriction that array section lower bound must be non negative.
This change is to allow negative values for array section based on pointers.
For array section based on array type there is still a restriction: "The array section must be a subset of the original array."

Kelvin Li 9f645ae63b [OpenMP] Fix incorrect diagnostics in map clause
Having the following code pattern will result in incorrect diagnostic

int main() {
  int arr[10];
