Use a RAII object to manage the lifetime of the reproducer
instrumentation data.

Originally committed as 416fa772
Reverted (due to buildbot failure - breaking lldb) in 7a45aeac.

I still can't seem to build lldb locally, but Pavel Labath has kindly
provided a potential fix to preserve the old behavior in lldb by
registering a simple recoverable error handler there that prints to the
desired stream in lldb, rather than stderr.

The inversePermutation method returns a null map on failure. Update
uses of this method within Linalg to handle this. In LinalgToLoops the
null return value was used to emit scalar code. Modify that to return
failure, and emit scalar implementation when affine map is "empty",
i.e. 1 dims, 0 symbols and no result exprs.

Summary:
wasm-ld requires --shared-memory to be passed when the atomics feature
is enabled because historically atomic operations were only valid with
shared memories. This change relaxes that requirement for when
building relocatable objects because their memories are not
meaningful. This technically maintains the validity of object files
because the threads spec now allows atomic operations with unshared
memories, although we don't support that elsewhere in the tools yet.

This is useful when replaying tests after the fact and the directories
don't exist anymore.

Summary:
This patch fix the following issues in InstCombiner::visitGetElementPtrInst

    1. Skip for scalable type if transformation requires fixed size number of
    vector element.
    2. Skip for scalable type if transformation relies on compile-time known type
    alloc size.
    3. Use VectorType::getElementCount when scalable property is used to construct
    new VectorType.
    4. Use TypeSize::getKnownMinSize when minimal size of a scalable type is valid to determine GEP 'inbounds'.
    5. Explicitly call TypeSize::getFixedSize to avoid implicit type conversion to uint64_t.

With this patch, .verify.cpp tests explicitly require clang-verify, but
no other test types require clang-verify out of the box. This will allow
making several .fail.cpp tests that don't have any clang-verify markup
to be just .compile.fail.cpp tests, which in turn should allow removing
a long standing workaround that requires parsing tests to detect whether
they have any clang-verify markup in them.

This allows AntiDepBreaker to be used in target specific postRA
scheduler.

GCC emits this new form along with others forms(supported in llvm-dwardump)
and since it's support was missing in llvm-dwarfdump, it was not
able to correctly dump the content a debug_macro section for GCC
generated binaries.

This patch extends llvm-dwarfdump to support this form,
now GCC generated debug_macro section can be correctly dumped
using llvm-dwarfdump.

Summary:
Only first-faulting and non-faulting loads read/update the FFR register
and hence only the corresponding SDNodes should be decorated with
`SDNPOptInGlue` and `SDNPOutGlue`. This patch:
  * removes SDNPOptInGlue from regular loads stores (FFR is not read)
  * adds SDNPOutGlue to first-faulting and non-faulting loads (FFR is
    both read and updated)
