d422e6f9b5 Add the start of libc and libstand for arm64. Not all of the machine
dependent functions have been implemented, but this is enough for world.

4bcb1430a8 Import jemalloc a8f8d7540d66ddee7337db80c92890916e1063ca (dev branch,
prior to 3.0.0 release).  This fixes several bugs related to memory
initialization.

Mangle __jemalloc_a0{malloc,calloc,free}() just like all the other
library-internal symbols in jemalloc, and adjust the tls allocation code
in libc to use the mangled names.

a4bd5210d5 Import jemalloc 9ef7f5dc34ff02f50d401e41c8d9a4a928e7c2aa (dev branch,
prior to 3.0.0 release) as contrib/jemalloc, and integrate it into libc.
The code being imported by this commit diverged from
lib/libc/stdlib/malloc.c in March 2010, which means that a portion of
the jemalloc 1.0.0 ChangeLog entries are relevant, as are the entries
for all subsequent releases.

54da2fb8f2 - Switch ARM and MIPS to TLS Variant I
- Fix TLS allocation  for Variant I: both rtld and libc allocators
    assume that tls_static_space includes space for TLS structure.
    So increment calculated static size by the size of it.

9436852167 The static TLS size as given by tls_static_space includes TLS_TCB_SIZE
bytes of TCB in variant I.

dfe2d491c0 o Add MIPS to the list of architectures with defined TLS_TCB_ALIGN
o Stick with TLS Variant II for MIPS for the moment.

0031cdf4d7 Don't assert() the TLS allocation requested is big enough; just
fix the argument.

In particular, this is a step towards breaking crt1's dependence on stdio.

3614156c7d Fix the variant I allocation for KSE: Allow a larger TCB and assume
that the documented TCB is at the tail of the extended TCB. In other
words, the base of the TCB has a negative offset from the TLS.
