RFR: 8035057: NewSize ergonomics wrong when setting small or unaligned size on command line

[Jon Masamitsu]

Stefan,

I got side tracked on this review.  I thought that the macro
FLAG_IS_CMDLINE would remember if the flag was sent on
the command line.  Unfortunately, it does not.

Is the problem that NewSize is set somewhere with
FLAG_SET_ERGO when it should not have been?
That is, if it has been set on the command line,
it should not be reset ergonomically.
