The following fixes an issue I found when more aggressively 
constant-folding from static initializers.  The Java frontend
fails to provide an initializer for the classdollar field
it creates but nevertheless marks them with TREE_READONLY
whilst being static.

Thus the following patch removes setting of TREE_READONLY.

Bootstrap & regtest running on x86_64-unknown-linux-gnu.

Ok?

Thanks,
Richard.
