[9] RFR (S) 8069111: Investigate NMT detail tracking support for 32bit ARM

[Chris Plummer]

Please help with the review for the changes for JDK-8069111:

Webrev: http://cr.openjdk.java.net/~cjplummer/8069111/webrev.06/
Bug: https://bugs.openjdk.java.net/browse/JDK-8069111

Tested with JPRT, including running all NMT tests and vmerror.sh.

Many of the changes are in closed code. For the open code, the main 
changes are to no longer support the 
PLATFORM_NATIVE_STACK_WALKING_SUPPORTED macro, and no longer allow 
platforms to include NMT but not include NMT Detail support. The NMT 
tests have been modified to reflect this. They no longer check if NMT 
Detail is supported and adjust the testing based on this. The removal of 
@ignore in some tests is because the cause of these test failures is 
fixed in the closed changes.

thanks,

Chris
