Use /data/local/tests/unrestricted as on-device test path so that
debuggerd can generate proper back traces.

For convenience, builds against musl libc currently use the
linux_glibc properties because they are almost always linux-specific
and not glibc-specific. In preparation for removing this hack,
tweak the linux_glibc properties by either moving them to host_linux,
which will apply to linux_glibc, linux_musl and linux_bionic, or
by setting appropriate musl or linux_musl properties. Properties
that must not be repeated while musl uses linux_musl and also still
uses the linux_glibc properties are moved to glibc properties, which
don't apply to musl. Whether these stay as glibc properties or get
moved back to linux_glibc later once the musl hack is removed is TBD.

Auto-generate NOTICE files for all the directories, and for each one
individually rather than mixing libc and libm together.

The benchmark calls __cxa_atexit 100000 times, then either exits early
without calling the destructors (_Exit) or exits normally, calling them
(exit).

The benchmark creates a set of DSOs that mimic the work involved in
loading the current version of libandroid_servers.so. The synthetic
benchmark has roughly the same number of libraries with roughly the same
relocations.
Currently, on a local aosp_walleye build that includes recent performance
improvements (including the Neon-based CL
I3983bca1dddc9241bb70290ad3651d895f046660), using the "performance"
governor, the benchmark reports these scores:

This reverts commit 3bf27c86d1.
Disable the 32-bit glibc target. We're not interested in benchmarking that
target, and the bench_noop_nostl executable doesn't build when ASAN is
turned on, because the libclang_rt.asan_cxx-i386.a lib contains
ubsan_type_hash_itanium.cc.o, which needs __dynamic_cast and various
STL typeinfo variables. The equivalent libclang_rt.asan_cxx-x86_64.a
lib doesn't have ubsan_type_hash_itanium.cc.o in it.

Specifically, test the wall-clock time for running:
* a C program that does nothing (i.e. no STL)
* a C++ program that does nothing
* a statically-linked C++ program
* toybox true (in /system/bin and /vendor/bin)
* mksh -c true (in /system/bin and /vendor/bin)
