Attempt to fix the test failures observed in CI: * Add Option dependency, which caused BUILD_SHARED_LIBS builds to fail * Adapt tests that accidentally depended on the host platform: platforms that don't use an integrated assembler (e.g. AIX) get a different set of commands from the driver. Most dependency scanner tests can use -fsyntax-only or -E instead of -c to avoid this, and in the rare case we want to check -c specifically, set an explicit target so the behaviour is independent of the host. Original commit message follows. --- Instead of trying to "fix" the original driver invocation by appending arguments to it, split it into multiple commands, and for each -cc1 command use a CompilerInvocation to give precise control over the invocation. This change should make it easier to (in the future) canonicalize the command-line (e.g. to improve hits in something like ccache), apply optimizations, or start supporting multi-arch builds, which would require different modules for each arch. In the long run it may make sense to treat the TU commands as a dependency graph, each with their own dependencies on modules or earlier TU commands, but for now they are simply a list that is executed in order, and the dependencies are simply duplicated. Since we currently only support single-arch builds, there is no parallelism available in the execution. Differential Revision: https://reviews.llvm.org/D132405
