RFR 8234270: [REDO] JDK-8204128 NMT might report incorrect numbers for Compiler area

[Zhengyu Gu]

JDK-8204128 did not fix the original bug. But new assertion helped to 
catch the problem, as it consistently failed in Oracle internal tests.

The root cause is that, when NMT biases a resource area to compiler, it 
did not adjust tracking data to reflect that. When the biased resource 
area is released, there is a possibility that its size is greater than 
total size recorded, and underflow a size_t counter.

JDK-8204128 patch also missed a long to ssize_t parameter type change, 
that resulted new test failure on Windows, because long is 4-bytes on 
Windows.

Many thanks to Leonid Mesnik, who helped to run this patch through 
Oracle's internal stress tests.
