in a recent code cleanup I accidentally removed setting of
lrg._was_spilled1/2, missing a few cases where they were actually in
use. This cause a severe performance degradation in some benchmarks like
Octane Richards.

Restore calculation of lrg._was_spilled1/2.

Bug:    https://bugs.openjdk.java.net/browse/JDK-8217716
Webrev: http://cr.openjdk.java.net/~redestad/8217782/open.00/

Testing: verified locally that performance in Octane Richards is back to
normal levels, running tier1+2
