The module cache escapes the test output dirs in this test. Since its default location maybe
composed of system and user related path this can cause problems in some builders (e.g. not
accessible paths inherited in a chroot environment).
Clean the test a bit by passing `-fmodules-cache-path` inside the test output dirs.

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.
