[It appears that a bunch of old cros issues bulk-added the "Infra" component recently, but they should probably be "Infra>Client>ChromeOS".]

Create compilation and runtime test for toolchain

This CL creates two packages:
  1. autotest-tests-toolchain adds `platform_ToolchainTests' to autotest
     and creates the dependency indirectly between autotest and
     toolchain-tests.
  2. toolchain-tests is the place where runtime tests are built and
     compilation test are done.  The tests are stored in autotest's
     repository.

Compilation and runtime tests for toolchain

This is a framework that hosts compilation and runtime tests for
Chrome OS toolchain.  Currently, it contains:
  1. a dummy compilation test that prints 'checking compiler
     errors/warnings'
  2. a dummy autotest client test that runs a prebuilt binary which
     always returns success.
