check break target correctly.
* compile.c (iseq_compile_each0): save target child_iseq in the catch-table
for break. This iseq is not for continuation, but for search key at
vm_throw_start().
* vm_insnhelper.c (vm_throw_start): check saved iseq first.
* iseq.h: add comment for it.
* test/ruby/test_iterator.rb (test_ljump): add a test for the issue:
def call b; b.call; end
call(Proc.new{break}){} #=> (1) should raise LocalJumpError
call(Proc.new{break}) #=> (2) shoudd raies LocalJumpError, too.
but (1) doesn't raise LocalJumpError.
