SWDEV-95698 - Complib: set data layout string from the subtarget in codegen
This logic was broken since llvm 3.6 merge and datalayout was not set as supposed.
This results in a different compilation results with complib and llc.
In addition that leads to the suboptimal codegen.
Testing: smoke, precheckin, llc_opt, ocl_features, vec_ldst, ocl_sdk_aoc2_compare_main
