* heap.cc (eval_initial_heap_size): New function fetching the heap

	size from the LoaderFlags field in the PE/COFF header.
	(heap_init): Call eval_initial_heap_size rather than
	cygwin_shared->heap_chunk_size to fetch the initial heap size.
	* shared.cc (shared_info::heap_chunk_size): Remove.
	* shared_info.h (class shared_info): Drop heap_chunk member.
	(CURR_SHARED_MAGIC): Update.
