re PR middle-end/37448 (cannot compile big function)

2008-10-07  Kenneth Zadeck <zadeck@naturalbridge.com>

	PR rtl-optimization/37448
	alloc_pool_desc (elt_size): New field.
	alloc_pool_desc (created, allocated, current, peak): Make unsigned
	long.
	output_info (count): Renamed total_created and made unsigned long.
	output_info (size): Renamed total_allocated and made unsigned long.
	alloc-pool.c (create_alloc_pool, empty_alloc_pool, pool_alloc,
	pool_free): Properly keep track of desc->size.
	(print_statistics, dump_alloc_pool_statistics): Enhance the
	printing of statistics to print the number of elements and to use
	unsigned longs.
