sys-devel/clang: Build tests in src_compile()

Build tests in src_compile() (when enabled) rather than delaying that
until src_test(). This ensures a better split between compilation phase
and testing in multilib builds, i.e. you can turn off other distcc
servers when first ABI starts testing. Also, it guarantees that building
the tests will be tested for all ABIs, even if the actual tests fail for
one of them.
