Disabled VNDK libraries (due to arch mismatch) are no longer emitted to
make variables VNDK_CORE_LIBRARIES and LLNDK_LIBRARIES
Bug: 7456955
Test: choosecombo to aosp_walleye and m -j
Find libclang_rt.ubsan_standalone-<arch>-android in VNDK_CORE_LIBRARIES.
Only aarch64 and arm are found.

Such optimisations may significantly increase the binary size when
compiler heuristics are off. Disabling these helps cut down the
binary sizes with negligible decrease in performance, but allows us to
be more comfortable enabling LTO across various projects.

LLVM-AR does not allow passing --plugin options more than once. The
--plugin ARFLAGS that lto want to add, may already exist if sanitizer is
also turned on.
Fixed this by adding a new bool Flags.ArGoldPlugin. Set this variable to
true whenever LLVM gold plugin is needed for ArFlags. In function
TransformObjToStaticLib(), add this option to arFlags using global value
${config.LLVMGoldPlugin} if the bool value is true.

This variable can be set in BoardConfig.mk to specify a list of
additional paths that contain PGO profiles. These directories are
searched after the predefined paths in soong/cc/pgo.go while finding
PGO profiles.
Test: Set this variable in a BoardConfig and verify that such profiles
are found and that these paths are searched after the predefined paths
in soong/cc/pgo.go.

-fsanitize=cfi requires LTO. Normally, the Clang driver automatically
enables emutls, but it's broken with -flto, so work around it by passing
-Wl,-plugin-opt=-emulated-tls.

Enable the workaround with ctx.Device(), which is the same condition used
in the existing I18acac41aac885fc6635fbd55f96ba7c845eb5e7 workaround.

Store missing profile files and the modules that refer to them in the
SOONG_MODULES_MISSING_PGO_PROFILE_FILE variable passed to Make. The
contents of this variable will be written to
$DIST_DIR/pgo_profile_file_missing.txt as part of the 'dist' target.
Test: 'm dist' and verify creation of pgo_profile_file_missing.txt.

For the VNDK prebuilt modules that does not match the target arch,
skip installing the module instead of marking the module to prevent

Change https://android-review.googlesource.com/c/572758, in addition to
dependencies from the compiler flags, also marked all exported
dependencies as implicit. This can cause lots of unnecessary
recompiles. This change moves exported dependencies back as order-only
dependencies.
Test: 1. mma in art after changing profile_compilation_info.h triggers
only a limited number of recompiles.
2. verify that changes to PGO profile files trigger recompiles.

This commit adds `extends: "name"` property and provides basic support
to VNDK extensions. This is the simplest example:
```
cc_library {
name: "libvndk",
vendor_available: true,
vndk {
enabled: true,
},
}
cc_library {
name: "libvndk_ext",
vendor: true,
vndk: {
enabled: true,
extends: "libvndk",
},
}
```
A vndk extension library must extend an existing vndk library which has
`vendor_available: true`. These two libraries must have the same
`support_system_process` property.
VNDK-ext libraries are installed to `/vendor/lib[64]/vndk` and
VNDK-SP-ext libraries are installed to `/vendor/lib[64]/vndk-sp` by
default.
If there is a matching abi-dumps in `prebuilts/abi-dumps`,
`header-abi-diff` will be invoked to check for ABI breakages.

call it from a HIDL service.
