Optimize: `return (a ? b : c)' as: `if (a) return b; else return c;'.
Optimize: `return (a ? b : c)' as: `if (a) return b; else return c;'.
* jcf-write.c (generate_bytecode_return): New function.
(generate_bytecode_insns): Use it, for RETURN_EXPR.
* jcf-write.c (generate_bytecode_insns): For REAL_CST that is 0 or 1,
generate special [fd]const_[01] instructions.
* jcf-parse.c (yyparse): Don't emit_register_classes if -fsyntax-only.
* verify.c (verify_jvm_instructions): Do INVALIDATE_PC after
handling OPCODE_lookupswitch or OPCODE_tableswitch.
