[lldb] [lit] Add feature flags for native CPU features

Add a new lit-cpuid tool that detects CPU features used by some of
the tests, and use it to populate available_features in lit.  For now,
this means that the test for MM/XMM register read will be run only
when the host CPU support SSE instruction set.  However, this is going
to make it possible to introduce additional tests relying on AVX.
