8026324: hs_err improvement: Add summary section to hs_err file 8026333: hs_err improvement: Print GC Strategy 8026336: hs_err improvement: Print compilation mode, server, client or tiered Summary: Added command line, summary cpu and os information to summary section. Moved time of crash and duration in summary section. Add GC strategy and compiler setting (tiered) to enhanced version string in error report. Moved the stack trace sooner in hs_err file.
