Here are the requested additional fixes for vector_ideal_reg and
vector_shift_count_ideal_reg.

full: http://cr.openjdk.java.net/~kbarrett/8160748/hotspot.01/
incr: http://cr.openjdk.java.net/~kbarrett/8160748/hotspot.01.inc/

Note that I've not tested the aarch64, ppc, or s390 changes at all.
They are pretty simple though, so hopefully no problems.
