RFR: 8371320: runtime/ErrorHandling/PrintVMInfoAtExitTest.java fails with unexpected amount for Java Heap reserved memory [v2]

[Paul Hübner]

> Hi all,
> 
> In [JDK-8364741](https://bugs.openjdk.org/browse/JDK-8364741) it was discovered that asan reserves a bit more heap. The test got patched by checking for asan and adjusting the expectation, respectively.
> 
> It turns out that, rarely, we do reserve more memory even without asan enabled. This change updates the test:
> a) to ensure that some sort of reservation size is reported; and
> b) to extract the reserved amount and assert that it is no less than the committed amount
> 
> Testing: Ran tier1. Stress tested the individual test with 5x100 repetitions per platform (Linux x64, AArch64; macOS x64, AArch64; Windows x64).
