RFR: Upstream merge 2018-06-30

[Roman Kennke]

Ok, it's done. Now it's merged up to the last changeset that is common
between jdk/jdk and jdk/jdk11, which is this one:

changeset:   51321:95aad0c785e4
user:        gadams
date:        Thu Jun 28 10:31:39 2018 -0400
summary:     8205508:
hotspot/jtreg/vmTestbase/nsk/jdb/exclude/exclude001/exclude001.java
fails with Prompt is not received during 300200 milliseconds.

From there we can fork shenandoah/jdk11 and update that one from
jdk/jdk11, and pull the remaining stuff from jdk/jdk into shenandoah/jdk.

The diff of Shenandoah changes (now including x86 and aarch64 too):

Testing (ongoing): tier3_gc_shenandoah (fastdebug/non-PCH release/non-PCH)
