This is not explored on Android properly and no one should use it until
proper scientific testing.
Moreover, THP is broken with all recent Qualcomm devices due to
speculative page faults.

Before, libc was adding the include directories directly. Instead,
add it to the export list to it can be added automatically.

It was found that keeping just a few allocations of the same size around
(even up to only 3) increases the allocation time significantly. This
appears to be because I set the minimum tcache entries to 1. Removing this
and the performance comes mostly all of the way back. There is still
some loss, but probably just due to a different bin layout than jemalloc
4.x.
This does increase the PSS slightly for many processes. About 1MB
in my trace runs. However, it increases the performance of most
multiple allocations by a factor of three.
Bug: 129743239
Test: Ran memory_replay on all traces.
Test: Ran new bionic benchmarks to verify things get better.

It was discovered that we were building some objects inconsistently due
to an optimization in cc_library to only build objects once and use them
for both the static and shared libraries. But static libraries didn't
get system_shared_libs set automatically, and we didn't notice that we
would have built the objects differently.
So static libraries now get the default system_shared_libs, we allow
adjusting that for static vs shared in a cc_library, and we disable the
optimization if the linked libraries are configured differently between
static and shared in a single cc_library.
This triggers dependency cycles for static libraries that libc/libdl
use, so fix those cycles here.
Test: treehugger

Add support for svelte.
Add je_iterate support.
Update some of the internals so that bad pointers in je_iterate do not
crash.
Test: Ran new bionic unit tests, ran libmemunreachable tests, booted system.

This does not add any android specific changes. Those will come in a
follow-up cl.
Test: Builds, and all unit tests pass on a hikey.
