avoid redundant GET_THREAD() calls
This reduces binary size slightly on my 32-bit system:
text data bss dec hex filename

2847641 12360 30632 2890633 2c1b89 ruby
* iseq.c (rb_iseq_compile_with_option): reuse result of previous
GET_THREAD() call
* thread.c (thread_create_core): ditto
(rb_mutex_trylock): ditto
(rb_mutex_lock): ditto
* process.c (rb_waitpid): avoid multiple eval from RUBY_VM_CHECK_INTS
* thread.c (rb_thread_check_ints): ditto
