gc.c (rb_imemo_alloc_new): split for each purpose

imemo_alloc is used for three purposes: auto-free pointer (alternative
of alloca), alloc_tmp_buffer, and heap allocation for bison.
To make it clear, this change introduces three functions:
rb_imemo_alloc_auto_free_pointer,
rb_imemo_alloc_auto_free_maybe_mark_buffer, and
rb_imemo_alloc_parser_heap.
