RFR(S): 8217658 baseline_cleanups from Async Monitor Deflation project

[Daniel D. Daugherty]

Greetings,

I have a (S)mall patch extracted from the Async Monitor Deflation
project that is ready for code review.

The short version of what this patch is about:

     This sub-task captures updates to the baseline code that are not
     directly related to Async Monitor Deflation.

The details are in the bug report:

     JDK-8217658 baseline_cleanups from Async Monitor Deflation project
     https://bugs.openjdk.java.net/browse/JDK-8217658

Here's the webrev:

     http://cr.openjdk.java.net/~dcubed/8217658-webrev/0-for-jdk13/

This patch along with the other two patches for Async Monitor Deflation
project have been through Mach5 
builds-tier1,hs-tier1,jdk-tier1,hs-tier2,hs-tier3
testing and I'm currently running my stress testing kits on my Linux-X64
and Solaris-X64 servers.

Thanks, in advance, for any questions, comments or suggestions.

Dan
