RFR 8035074: hs_err improvement: Add time zone information in the hs_err file (+8026335 and 8026331)

[Coleen Phillimore]

This is actually changes for 3 RFE's for hs_err file reporting:

8035074: hs_err improvement: Add time zone information in the hs_err file
8026335: hs_err improvement: Print exact compressed oops mode and the 
heap base value.
8026331: hs_err improvement: Print if we have seen any OutOfMemoryErrors 
or StackOverflowErrors
Summary: Add requested things to hs_err file.

Tested manually with crashes in vm_exit.  Fun fact, the jtreg tests 
report that they passed:
https://bugs.openjdk.java.net/browse/JDK-8085909

Also tested with runThese jck tests with small metaspace and compressed 
class space to get exception counts.

New lines in hs_err_pid file (don't have plus in them, just for 
illustration):

VM Mutex/Monitor currently owned by a thread: None
+
+OutOfMemory and StackOverflow Exception counts:
+OutOfMemoryError java_heap_errors=2
+OutOfMemoryError class_metaspace_errors=7
+StackOverflowErrors=2
