Inline tcache functions
The functions tcache_get and tcache_put show up in profiles as they are a critical part of the tcache code. Inline them to give tcache a 16% performance gain. Since this improves multi-threaded cases as well, it helps offset any potential performance loss due to adding single-threaded fast paths. * malloc/malloc.c (tcache_put): Inline. (tcache_get): Inline.
