RFR (XS): JDK-8033990: Add message to verbose output to indicate when JVM was unable to use shared archive (with -Xshare:auto)

[Mikhailo Seledtsov]

Hi Coleen,

  Thank you for the review. Would it be OK if I print the message that 
comes thru after the message that I introduced?

There is a variety of messages that are passed to fail_continue() 
depending on who calls it; checking/asserting on each message in the 
test would be a large overhead; also some of these messages do not 
convey "attempted, but failed" meaning.

Thank you,
Misha
