RFR (M): Use TSAN_RUNTIME_ONLY for most instrumentation

[Man Cao]

Hi all,

Can I have reviews for this bug fix and cleanup?
http://cr.openjdk.java.net/~manc/tsan/20190506/webrev.00/

Copying commit message below:
Use TSAN_RUNTIME_ONLY for most instrumentation.
This fixes build error using --with-jvm-features=-tsan,
and reduces boilerplate code for instrumentation.
Also simplified oopDesc:is_oop() uses and updated a comment.
