RFR: 8287830: gtest fails to compile after JDK-8287661

[Jie Fu]

Hi all,

gtest fails to compile when configured with `--with-debug-level=optimized`.

This is because for `optimized` no `PRODUCT` is defined.

ifeq ($(DEBUG_LEVEL), release)
  # For hotspot, release builds differ internally between "optimized" and "product"
  # in that "optimize" does not define PRODUCT.
  ifneq ($(HOTSPOT_DEBUG_LEVEL), optimized)
    JVM_CFLAGS_DEBUGLEVEL := -DPRODUCT
  endif


And the `test` log tag is only defined for DEBUG versions.

  LOG_TAG(table) \
  LOG_TAG(task) \
  DEBUG_ONLY(LOG_TAG(test)) \
  LOG_TAG(thread) \
  LOG_TAG(throttle) \


So let's fix it.

Thanks.
Best regards,
Jie
