LOG: [PollyACC] Fix implicit function definitions. NFC.

The isl_id_* have been in used without including the correspodning
isl/id.h header. According to rules in C, a function is defined
implicitly when first used with an assumed int return type (32 bits on
64 bit systems). But the implementation returns a pointer (64 bits on 64
bit systems). Is usually has no consequence because the return value is
stored in a registers that is 64 bits (RAX) and the optimizer does not
truncate its value before using it again as a pointer value. However,
LTO optimizers will be rightfull;y confused.

Fix by including <isl/id.h>

This fixes llvm.org/PR50021
