fixes enum bug in isEqual generation

Fix for a comparison bug in enums in generated code
avoid "local ... hides instance variable" warnings in generated code

GCC gets upset if you hide an instance variable with a local variable
and issues a warning that apparently can't be turned off.  This commit
renames the "size" local variable in the serializedSize generated
method so it doesn't hide the instance variable.  It also renames the
"value" parameter to the setHasFoo: methods to avoid hiding a field
named "value" if it happens to exist.
