java-tree.h, [...]: Remove all #if JAVA_USE_HANDLES blocks...
* java-tree.h, class.c, expr.c, jcf-parse.c, parse.y,
typeck.c, verify.c: Remove all #if JAVA_USE_HANDLES blocks,
all mention of CLASS_TO_HANDLE_TYPE or HANDLE_TO_CLASS_TYPE,
and all now-pointless local variables. Rename other local
variables to reflect their not being handles.
* java-tree.h, jcf-dump.c, jcf-io.c: Remove all
#if JCF_USE_STDIO blocks.
* parse.y: Add missing semicolon at end of rule.
