8303215: Make thread stacks not use huge pages

[tstuefe]

Backported for parity with Oracle and as preparation to fix https://bugs.openjdk.org/browse/JDK-8312182.

Backport is unclean, but the difference is minor. I had to adjust hunks in os::large_page_init() since the surrounding coding changed a lot since JDK 11.

@gnu-andrew maybe ?

[phohensee]

At the start of os::large_page_init(), there's an extra blank line after the method signature. Otherwise fine.

HI,

I am facing a bug described in JDK-8312182 and would like to apply the JDK-8312182's fix to jdk11 and jdk8.

Could you reopen this PR and issue a Fix Request?

Thanks.

@tstuefe

Sorry to bother you, but I'd appreciate it if you could check #2208 (comment).
If you don't have time to reopen and work on this, I will consider creating a new pull request myself.

Thanks.

[phohensee]

@kurashige23, you could also just file new PRs.
