[PATCH] Fix PR64044

Mon Nov 24 12:36:00 GMT 2014

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.
