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.
