1b017a76e1 Hide CFI behind a global flag.
This CL ensures that locally enabling CFI in a .bp file is not honored
unless it is enabled globally using ENABLE_CFI=true first, effectively
hiding it behind a flag.

Bug: 30227045
Bug: 22033465
Test: m -j40 works and device boots
Test: cfi is correctly honored only when the global flag is set.

23ae82a2b2 Support sanitizing a single device arch
Allow specifying one or more architectures to sanitize for.  Defaults to
sanitizing all architectures.  Allows reducing the cost of sanitization
by only sanitizing half of the platform.

1e405e160a [soong] Enable LOCAL_SANITIZE:=cfi and add LOCAL_SANITIZE_DIAG.
LOCAL_SANITIZE_DIAG works for ubsan, too.

Bug: 22033465
Test: build a test target with cfi and diag { cfi } properties.

46974e2457 Don't pass -Wl,--no-undefined to host targets
Host builds were compiling without -Wl,--no-undefined because of an ASAN
issue.  Pass -Wl,--no-undefined for host builds unless sanitzers are
enabled.  Also fix LOCAL_ALLOW_UNDEFINED_SYMBOLS on darwin, where
disallowing undefined symbols is the default.

Test: m -j host
Test: m -j SANITIZE_HOST=address host

b0f28957ae Support mixed ASAN and non-ASAN host builds
Host builds may build binaries that must have ASAN disabled.  Convert
host ASAN to use variants.  Since there is only one install location for
shared libraries, don't install the non-ASAN variant at all for now.

Test: mmma -j art SANITIZE_HOST=address

b916a38233 Refactor cc modules to use decorators instead of inheritance
For example , instead of trying to have libraryLinker inherit from
baseLinker and libraryCompiler inherit from baseCompiler, create a
single decorator object that wraps both baseLinker and baseCompiler.

Test: Builds, no unexpected changes to build.ninja

fcfe56d194 Target sanitize properties can disable the global sanitizer.
With this change, sanitize: { address: false } disables
SANITIZE_TARGET=address for one target.

Also rename SafeStack to Safestack, because the former can not be
used as a target property.
