Make dlmalloc 2.4x faster for multithreading

Browse source 
This change adds a TLS freelist for small dynamic memory allocations.
Cosmopolitan's TIB is now 512 bytes in size. Single-threaded malloc()
performance isn't impacted by this, until pthread_create() is called.
Single-threaded programs may also want to consider using:

    #include "libc/mem/tinymalloc.inc"

Which will shave 30k off the executable size and sometimes go faster.
