This commit adds support for the VM_METHOD_TYPE_BMETHOD method type in
YJIT. You can get these type of methods from facilities like
Kernel#define_singleton_method and Module#define_method.
Even though the body of these methods are blocks, the parameter setup
for them is exactly the same as VM_METHOD_TYPE_ISEQ, so we can reuse
the same logic in gen_send_iseq(). You can see this from how
vm_call_bmethod() eventually calls setup_parameters_complex() with
arg_setup_method.
Bmethods do need their frame environment to be setup differently. We
handle this by allowing callers of gen_send_iseq() to control the iseq,
the frame flag, and the prev_ep. The prev_ep goes into the same
location as the block handler would go into in an iseq method frame.
