RFR: 8149996: TraceLoaderConstraints has been converted to Unified Logging.

Why did you take out the ResourceMarks at line 130, 160, 231 and 244, 
297, 308 and 357?

Unfortunately, we really need log_info_rm(tag)("String") call because 
all those places need a ResourceMark.

Anytime we call name()->as_C_string() there needs to be a ResourceMark 
in the scope of the call.
