Subject: * vm_insnhelper.c (vm_call_method): disable CI_SET_FASTPATH() if  
 this method call needs splat argument because cahced functions  
 (vm_call_attrset, vm_call_ivar, vm_call_cfunc_fast_(unary|binary))   do not
 check an arity. * bootstraptest/test_method.rb: add a test to check an above
 issue.
