Test and ASan output

AddressSanitizer detects a heap-use-after-free in gbe::ir::Immediate::getIntegerValue() const when compiling latest master and running the test compiler_subgroup_media_block_read_us2, see the attached log.

Compilation command:
(Remove '-Wl,--no-undefined' from CMakeLists.txt)
$ cmake -G Ninja -DENABLE_OPENCL_20=false -DCOMPILER=CLANG -DCMAKE_C_FLAGS="-fsanitize=address -fno-omit-frame-pointer" -DCMAKE_CXX_FLAGS="-fsanitize=address -fno-omit-frame-pointer" -DCMAKE_SHARED_LINKER_FLAGS="-fsanitize=address" -DCMAKE_BUILD_TYPE=Debug ..
$ env ASAN_OPTIONS=alloc_dealloc_mismatch=0:detect_leaks=false ninja
$ env ASAN_OPTIONS=alloc_dealloc_mismatch=0:detect_leaks=false ninja utest
