Wilco Dijkstra 3f6bb8a32e Add single-threaded path to malloc/realloc/calloc/memalloc 
This patch adds a single-threaded fast path to malloc, realloc,
calloc and memalloc.  When we're single-threaded, we can bypass
arena_get (which always locks the arena it returns) and just use
the main arena.  Also avoid retrying a different arena since
there is just the main arena.

	* malloc/malloc.c (__libc_malloc): Add SINGLE_THREAD_P path.
	(__libc_realloc): Likewise.
	(_mid_memalign): Likewise.
	(__libc_calloc): Likewise.
