[10]RFR: 8176096: Wrong marco checks for INCLUDE_TRACE

[Robbin Ehn]

Hi all, please review.

INCLUDE_TRACE is set either 0 or 1.
Checks should be "#if INCLUDE_TRACE" and not "#ifdef INCLUDE_TRACE".

Bug: https://bugs.openjdk.java.net/browse/JDK-8176096
Webrev: http://cr.openjdk.java.net/~rehn/8176096/webrev/

Test built open and oracle.

Thanks Robbin
