[SYCL] Split optimization_level_debug_info test (intel#977)

The optimization_level_debug_info test can on some systems cause a
timeout due to the compilation time without optimizations and with
debug symbols enabled. To avoid this timeout, this commit splits the
test into two parts; one checking with integral optimization levels
(e.g. -O2) and one checking with special-name optimization levels
(e.g. -Og).
