avoid redundant GET_THREAD() calls

This reduces binary size slightly on my 32-bit system:

   text    data     bss     dec     hex filename
2847705   12360   30632 2890697  2c1bc9 ruby.orig
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
