We saw a failure caused by unwinding with incomplete CFIs, so we
can't outline CFI instructions when they are needed in EH.
This is a recommit of 0d40688, which was reverted in ce83883 as
related precommit test 360d44e caused some errors.

This wasn't accounting for the canonicalize of the input, or checking
the output fneg isn't folded as intended. Avoids test failure in
unrelated patch which happens to change register numberings.
Insert the select op before the combiner op when vectorizing a
reduction loop that needs a mask, so the vectorized reduction loop
can pass isLoopParallel check and be transformed correctly in later
passes.

Summary:
A new offloading action builder line was added that wasn't guarded with
the new driver for OpenMP. This doesn't affect anything now but could
potentially cause problems.
This reverts commit 414f84ba29.
Requires deirectives had already been added to the test, and CC1 tests
should use a target triple.

The motivation is twofold:
1) Allow plugging in a different training-time evaluator, e.g.
TFLite-based, etc.
2) Allow using TensorSpec for AOT, too, to support evolution: we start
by extracting a superset of the features currently supported by a
model. For the tensors the model does not support, we just return a
valid, but useless, buffer. This makes using a 'smaller' model (less
supported tensors) transparent to the compiler. The key is to
dimension the buffer appropriately, and we already have TensorSpec
modeling that info.
The only coupling was due to the reliance of a TF internal API for
getting the element size, but for the types we are interested in,
`sizeof` is sufficient.
A subsequent change will yank out TensorSpec in its own module.

D70524 added support for auto return types for C++ member functions. I was
implementing support on the LLDB side for looking up the deduced type.
I ran into trouble with some cases with respect to lambdas. I looked into
how gcc was handling these cases and it appears gcc emits the deduced return type for lambdas.
So I am changing out behavior to match that.

Fixes llvm-project/compiler-rt/test/asan/TestCases/null_deref.cpp on
macOS/aarch64.
The bp (base pointer) variable was being loaded from register LR and
not FP on aarch64 (except for this narrow case):
defined(__IPHONE_8_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0
Without a valid bp from the FP register, it is not possible to traverse
previous frames for a complete stack trace. The rationale for fetching
the LR as the bp for all cases except above is not clear but since the
FP register is the canonical register for use as the frame pointer, this
commit removes the restriction above for unconditional use all aarch64.

The first attempt at this missed a check to make sure the offset
constant was in range and caused many bot failures.
That was missed in the Alive2 proof because on overshift creates
poison rather than the assert from APInt. Here's an alternate
attempt at a proof using count-trailing-zeros:

Original commit message:
This is similar to an existing pre-shift-of-constant fold:

...but in this case, we need no-wrap on the shl and a negative
offset:
