Renamed the new jvm variant to "hardened".
As it is a hardened server build I'd prefer if that were somehow
reflected in the name. Though really I don't see why this should be
restricted this way ... to be honest I don't see hardened as a variant
of server vs. client vs. zero etc at all, you should be able to harden
any of those.
So IIUC with this change we will:
- always build JDK native code "hardened" (if toolchain supports it)
- only build hotspot "hardened" if requested; and in that case
- jvm.cfg will list -server and -hardened with server as default
Is that right? I can see that we may choose to always build Oracle JDK
this way but it isn't clear to me that its suitable for OpenJDK. Nor why
hotspot is selectable but JDK is not. ??
Sorry.

This patch defines flags for disabling speculative execution for

It defines a new jvm feature
no-speculative-cti, which is used to control whether to use the
flags for libjvm. It also defines a
new jvm variant "altserver" which is the same as server, but with
this new feature added.
I think the classic name for such product configuration is
"hardened", no?
I don't know. I'm open to suggestions on naming.
"hardened" sounds good to me.
The change looks good as well.
