528d67e523 Reland "Split the x86 host toolchain into glibc and musl variants"
Split the x86 host toolchain into glibc and musl variants

Create new musl toolchains that are based on the existing glibc
toolchains, and add the necessary flags for musl compiles.

This relands Ifc02f9e5afa61ff758be98b0c962f3a4b53d0546 with changes
for I46672e3a096b6ea94ff4c10e1c31e8fd010a163c.

vendor snapshot modules.  Move the data instead to a vendor_snapshot

04896cae35 Support memtag_heap in SANITIZE_TARGET_DIAG, fix cc_test interation.
cc_test without sanitize:memtag_heap acts as if it has implicit
sanitize{memtag_heap:true, diag:{memtag_heap:true}}. This is unaffected
by SANITIZE_TARGET.

Refactor the test to cover all permutations.

Change memtag include lists to act similar to SANITIZE_TARGET_DIAG: the
the sync include list upgrades async targets to sync, unless diag is
explicitly set to false in the target definition.

127bb8b9f6 Don't rewrite LLNDK dependencies with .llndk suffix
Rewriting LLNDK dependencies with .llndk suffix requries referencing
a global data structure to determine if a given library is an LLNDK
library and therefore needs the .llndk suffix.  References to
global data structures from mutators must be removed to support
incremental Soong analysis.  Instead, move the LLNDK stubs rules
into the vendor variant of the implementing cc_library so that
the original name can be used.

As an incremental step, the llndk_library modules are left in
place, and the properties are copied into the cc_library via
the dependency specified by the llndk_stub property.  A followup
will move the LLNDK properties directly into the cc_library and
delete the llndk_library modules.

The global list of LLNDK libraries is kept for now as it is used
to generate the vndk.libraries.txt file.

b024957791 Propagate all sanitizer flags in SDK snapshots.
liblog snapshot needs to sanitizer.address=false to avoid cycle in asan
builds. Adding that separately in library_sdk_member.go would start to
feel like whack-a-mole, so the snapshot generation is instead extended
to handle nested property structs.

This uses the BpPropertySet.AddProperty extension in
https://r.android.com/1423510, and common value optimisation now
recurses into non-anonymous structs, instead of comparing them as a
whole.

945441c09a Add exclude_from_vendor_snapshot property, related logic
When building a vendor snapshot, the general rule the
build system uses to select a module for inclusion into
the vendor snapshot is if it's a framework module.
However, there are cases where a partner may modify the
framework module, thereby assuming control of that
module.

This change adds the exclude_from_vendor_snapshot
property allowing the partner to mark a module that
would normally be included in the vendor snapshot for
exclusion. This module is then built from source when
building the vendor image against the vendor snapshot.

c42f2f2e9d Add cfi static libraries to vendor snapshot
CFI modules can't link against non-CFI static libraries, and vice versa.
So without capturing both CFI and non-CFI static libraries, vendor
modules won't be able to use CFI, which will be a critical security
hole.

This captures both CFI and non-CFI variants of all static libraries for
vendor snapshot, except for those whose cfi are explicitly disabled.

For example, suppose that "libfoo" is defined as follows.

cc_library_static {
    name: "libfoo",
    vendor_available: true,
}

As it doesn't have cfi disabled, two libraries "libfoo.a" and
"libfoo.cfi.a" will be captured. When installed, vendor snapshot module
for "libfoo" will look like:

vendor_snapshot_static {
    name: "libfoo",
    src: "libfoo.a",
    cfi: {
        src: "libfoo.cfi.a",
    },
}

The build system will recognize the "cfi" property, and will create both
CFI and non-CFI variant, allowing any modules to link against "libfoo"
safely, no matter whether CFI is enabled or not.

Two clarification:

1) The reason why we don't create separate modules is that DepsMutator
runs before sanitize mutators. CFI and non-CFI variant of a library
should exist in a single module.

2) We can't capture CFI variant if the source module explicitly disables
cfi variant by specifying the following.

sanitize: {
    cfi: false,
}

In this case, only non-CFI variant will be created for the vendor
snapshot module.

74d255698b Separate lists of soong sanitize modules
Dependencies of makefile modules are being redirected according to
SOONG_CFI_STATIC_LIBRARIES and SOONG_HWASAN_STATIC_LIBRARIES. But the
variables are shared among all variants (e.g. core, vendor, product,
arch), which can cause build error.

This splits the Makefile variables into several lists, one list per each
arch and each image variant, to correctly make the redirection.
