fix VM abort when ClassLoader.defineClass is used in bootimage build

Browse Source 
When loading a class which extends another class that contained a
field of primitive array type using defineClass in a bootimage=true
build, the VM was unable to find the primitive array class, and
makeArrayClass refused to create one since it should already have
existed.

The problem was that the bootimage=true build uses an empty
Machine::BootstrapClassMap, and resolveArrayClass expected to find the
primitive array classes there.  The fix is to check the
Machine::BootLoader map if we can't find it in
Machine::BootstrapClassMap.
