utests: Added unit tests to test LLVM and ASM dump generation in a two step build process with clCompile and clLink APIs.

    This patch adds two new tests to the unit tests. It uses the existing
    framework and data structures and tests the llvm/asm dump generation
    when these flags (-dump-opt-llvm, -dump-opt-asm) are passed as compile and link
    options to clCompileProgram and clLinkProgram APIs along with the dump file names.

    Method added:
    1) get_compile_llvm_info() tests LLVM dump generation after clCompileProgram() stage
    2) get_link_asm_info() tests Gen ASM dump generation after clLinkProgram() stage
