RFR: JDK-8001191: use -source 8 -target 8 when compiling the JDK

[Jonathan Gibbons]

Currently I believe jaxp, jaxws, corba default the boot javac (don't 
they) so are limited to -target 7.      It would be nice to fix that in 
build-infra, but in that case we would need to accomodate the difference 
in the compare images script.

It would also be nice to have some way of checking, at the end of the 
build, that all class files have the expected class file version, 
although that is less of a problem now that it used to be.
