We can save a significant amount of disk space by compressing
debug info in `lld` cc builds. This change configures a build
flag to instruct lld to compress debug info when building cc
libraries. Rather than adding a global config we add this to
each target individually to avoid linker failures on windows
cross build targets.

that were only used by an unused function. This removes most of the
references to GCC, although there are still some left in the host
toolchains.

Remove many of the overridden methods from toolchainBase in favor
of having smaller composable types. toolchainNoCrt, toolchain32Bit
and toolchain64Bit now only provide a few methods and can be mixed
in to any toolchain type. toolchainLinux, toolchainBionic,
toolchainWindows and toolchainDarwin now embed toolchainBase to provide
the default flags methods for when they don't override them.
This avoids the need for disambiguation methods required when a
type embeds two types that implement the same method.

* changes:
Fix crtend for musl static binaries
Support static_executable: true for musl builds
Use SystemSharedLibs as StaticLibs for static executables
Unlike glibc, musl does not #define __MUSL__ on the assumption that
building against musl will be done using a configure script that should
be testing for individual features rather than assuming them based on
using musl. We don't use configure-based builds, so add a local
ANDROID_HOST_MUSL macro that will be defined for all host musl builds.

This commit removes LinuxClangCppflags. Adding these `-isystem` flags

Bug: http://b/77792074
- Add the libclang_rt.profile runtime libraries directly to the compile
command (for both host and target) instead of relying on the Clang
driver.
- Move the coverage mutator to PreDepsMutators so the mutation has
already happened when runtime libraries are added during dependence
computation.
- Factor out cc/config/toolchain to identify libclang_rt.profile modules
for the x86 and x86_64 host.
Test: make NATIVE_COVERAGE=true produces coverage-enabled host binaries.

* USE_CLANG_LLD is unedefined in current builds.
* When USE_CLANG_LLD is defined to 'true' or '1',
use clang's lld instead of ld or ld.gold.
* When lld is enabled:
* ld-only flags are not passed to 'lld'.
* location_packer is disabled.
* Use new lld's --pack-dyn-relocs=android.
* When lld does not work:
* In Android.mk files use LOCAL_USE_CLANG_LLD := false.
* In Android.bp files use use_clang_lld: false.
* Only arm, arm64, x86, and x86_64_devices have LLD flags;
all other hosts and targets do not call lld yet.

Move all the flags that are used everywhere (or should be used
everywhere) into cc/config/global.go:
-no-canonical-prefixes
-fno-exceptions
-Wno-multichar
-O2
-g
-fno-strict-aliasing
Also remove flags that are already in noOverrideGlobalCflags:
-Werror=pointer-to-int-cast
-Werror=int-to-pointer-cast
x86 and x86_64 were specifying -fstrict-aliasing, but that was
being overriden later by -fno-strict-aliasing, so remove it.
ARM devices still override -fno-strict-aliasing to -fstrict-aliasing
when using ARM (vs. Thumb) instruction set.
