variables map between OpenMP and HardCloud buffer

[ciroceissler]

Consider the following example:

#pragma omp target device(HARPSIM) map(to: A, B, C) map(from: D, E, F, G, H)
#pragma omp parallel for use(hrw) module(loopback)
for (int i = 0; i < NI; i++) {
  // some code
}

In the hardware side, the IP developer expect the pattern below:

Variable	Buffer Number
A	0
B	1
C	2
D	3
E	4
F	5
G	6
H	7

However, this is not true because depend of the code inside the for loop.
