[LoopDeletion] Add test for PR49967 (NFC)

Test case for a SCEV invalidation bug caused by D100264, which
has since been reverted.

[TableGen] Use MachineValueTypeSet in place of SmallSet.

MachineValueTypeSet is effectively a std::bitset<256>. This allows
us quickly insert into the set and check if a type is in the set.

[lit] Fix the return code for "not not" after evaluating "not" internally

This fixes cases where "not not <command>" is supposed to return
only the error codes 0 or 1, but after efee57925c3f46c74c6697,
it passed the original error code through.

This was visible on AIX in the testcase,
where 'wc' returns 2, while it returns 1 on other platforms, and the
test required "not not" to normalize it to 1.

[Coroutines] Move CoroEarly pass to before AlwaysInliner

Presplit coroutines cannot be inlined. During AlwaysInliner we check if a function is a presplit coroutine, if so we skip inlining.
The presplit coroutine attributes are set in CoroEarly pass.
However in O0 pipeline, AlwaysInliner runs before CoroEarly, so the attribute isn't set yet and will still inline the coroutine.
This causes Clang to crash:
