Chandler Carruth b16cde9c53 Add a hack to support -cc1as. (#7083 )

This is (far) from robust -- particularly with repeated compiles in the
same address space. But it appears to be sufficient in the short term,
and we already have the relevant TODOs to factor this upstream into
something that we can use here.

This also somehow uncovered a bug in how we were logging failed commands
-- the failed commands are destroyed when we destroy the driver object
(and its diagnostics object), so we simply cannot do the logging _after_
flushing diagnostics. That's probably ok, and just doing this in the
other order makes the code simpler.

Extracted LLVM code

This directory holds code extracted from the LLVM project and used in various places in Carbon. This mostly happens when some logic isn't readily exposed in a library-suitable API, or needs excessive customization.

We separate the baseline code and customizations here as these are really derived from the LLVM project. However, both Carbon and LLVM use the same license, so linking these isn't a problem. We also use the standard Carbon banner at the top of these files as the license is accurate and the collection and arrangement of the code are part of Carbon. The code itself should be assumed to be derived from LLVM.

Whenever possible, we should eventually refactor the upstream code until the logic can be exposed and then we can depend on it rather than extracting it here.
