[lldb] Normalize paths in new test

The minidump-sysroot test I added in commit 20f84257 compares two paths
using a string comparison.  This causes the Windows buildbot to fail
because of mismatched forward slashes and backslashes.  Use
os.path.normcase to normalize before comparing.

Recommit [NFC] Refactor DiagnosticBuilder and PartialDiagnostic

This recommits 829d14ee0a6aa79c89f7f3d9fcd9d27d3efd2b91.

The patch was reverted due to a regression in some CUDA app
which was thought to be caused by this patch. However, investigation
showed that the regression was due to some other issues, therefore
recommit this patch.

[AArch64] Expand some vector of i64 reductions on NEON

With the exception of VECREDUCE_ADD, there are no NEON instructions to support vector of i64 reductions. This patch removes the Custom lowerings for those and adds some test coverage to confirm.

[SelectionDAG][GISel] Make LegalizeDAG lower FNEG using integer ops.

Previously, if a floating-point type was legal, but FNEG wasn't legal,
we would use FSUB.  Instead, we should use integer ops, to preserve the
semantics.  (Alternatively, there's a compiler-rt call we could use, but
there isn't much reason to use that.)

It turns out we actually are still using this obscure codepath in a few
cases: on some targets, we have "legal" floating-point types that don't
actually support any floating-point operations.  In particular, ARM and
AArch64 are using this path.

The implementation for SelectionDAG is pretty simple because we can
reuse the infrastructure from FCOPYSIGN.

See also 9a3dc3e, the corresponding change to type legalization.

Also includes a "bonus" change to STRICT_FSUB legalization, so we can
lower a STRICT_FSUB to a float libcall.

Includes the changes to both LegalizeDAG and GlobalISel so we don't have
inconsistent results in the future.

Fixes https://bugs.llvm.org/show_bug.cgi?id=46792 .
