I've reverted the message string back to saying "assert(" rather than
"vmassert(".  I'm working on getting an aurora test with the
"vmassert(" string to see how bad that change might be, but I'm not
sure I've done that properly yet.  Regardless, the argument for
reverting that string change seems pretty compelling.

I looked at what will happen with [vm]assert_status, which was
simplified to just expand into a vmassert rather than duplicating the
implementation of that macro.  The assert_status predicate expression
gets included in the message string in the same way under the new as
the old, so with vmassert message string reversion there won't be any
change here either.

I looked at assert_if_no_error similarly; it used to just expand into
assert and now expands into vmassert, so again no change in the
message.

For testing, I did builds with and without these changes, with
temporary code inserted to always fail an assertion, and verified that
the relevant message texts were identical.
