We can call directly into the blueprint bootstrap.bash using values that
soong_ui has already calculated.
Instead of calling into blueprint.bash, build minibp with microfactory,
and directly run ninja. This allows us to get individual tracing data
from each component.

Add armv8-a as a valid/supported 32-bit arm architecture variant. If
some known armv8-a core, like cortex-a53, cortex-a73, etc. is specified
as TARGET(_2ND)_CPU_VARIANT, the associated TARGET(_2ND)_ARCH_VARIANT
will be treated as if armv8-a is specified.

Test: "bionic-unit-tests-static --gtest_filter=*strlen*" on Nexus 4
(armv7-krait), emulator (armv7), and sailfish (armv8-kryo).
The test binary for the first 2 is built with armv7-a as its
TARGET_ARCH_VARIANT; The test binary for the last is built with
armv8-a as its TARGET_2ND_ARCH_VARIANT.
TARGET(_2ND)_CPU_VARIANTs of both binaries are set to "generic".

LL-NDK, VNDK-core, VNDK-SP libraries are exported to make as
SOONG_LLNDK_LIBRARIES, SOONG_VNDK_CORE_LIBRARIES, and
SOONG_VNDK_SAMEPROCESS_LIBRARIES. This can be used to auto-generate
ld.config.txt from a template.

Right now this is hard coded in two places (here and in
core/binary.mk). Keep it in one place so it's easier to change.

soong_build was writing a different make_vars-*.mk on every run
because the lists of vndk libraries were not sorted, causing
kati to regenerate the ninja file.

This wasn't intended to change the behavior, but it does slightly.
Previously any requests to acquire memory wouldn't block; only
(subsequent) requests for execution would block (if another
caller had already consumed the memory quota). Now the requests
for memory can also also block.
It turns out in a brief test on my computer that soong_zip
runs about 10 to 20% faster with this change than without it.
The final step involving soong_zip decreased from about
3.6 sec to about 3.3 sec in tests on my computer.
When testing the process of re-zipping the contents of
angler-target_files*.zip , the time decreased from about
6.3 sec to about 5.3 sec in tests on my computer, and the
peak memory usage reported by `top` decreased from about
1.5g to 1g

In LTO mode the backend constructs a target exclusively from command line flags,
without opportunity to accept code gen arguments from Clang. Clang does not
currently pass the -emulated-tls parameter for Android, even though it defaults
to emulated TLS for Android in non-LTO builds. Until this is fixed upstream, we
can explicitly specify that the LTO output for Android should use emulated TLS.
Test: build libandroid with LTO, verified that it uses __emutls_get_address
rather than __tls_get_addr.

Enabling the lto property for a module builds that module and all static
dependencies with LTO.
LTO (link-time optimization) allows the compiler to optimize and
generate code for the entire module at link time, rather than
per-compilation unit. LTO is required for Clang CFI and other
whole-program optimization techniques. LTO also allows cross-compilation
unit optimizations that should result in faster and smaller code, at the
expense of additional compilation time.
Test: make -j12 libc with lto: true for libc

Gold recognizes a different set of emulation strings to specify targets
than the bfd linker accepts. Clang only passes bfd emulations to the
linker, so we need to override these with the versions accepted by gold
when using gold.
Gold normally picks up the correct target from the first ELF input file
if it cannot parse the emulation parameter. However when using LTO, all
objects may be bitcode files, which causes gold to rely on the passed
--oformat or -m parameter to determine the proper target. If gold cannot
parse the emulation string passed by clang, it fails to link.
Test: build LTO version of libc
