This is a preparatory patch for allowing the GNU .debug_macro extension,
which is a precursor to the DWARF 5 format, to be emitted by LLVM for
earlier DWARF versions.
The entries share the same encoding and behavior as in DWARF5; there are
just more entries in the DWARF 5 format. Therefore, we could have used
those existing DWARF 5 entries, but I think that explicitly referring to
the GNU macro variants makes the code more clear.
The defines that this patch introduces can be found in GCC in the dwarf2.h header:

Two ubsan tests FAIL on Sparc:
UBSan-Standalone-sparc :: TestCases/TypeCheck/misaligned.cpp
UBSan-Standalone-sparcv9 :: TestCases/TypeCheck/misaligned.cpp
I've reported the details in Bug 47015, but it boils down to the fact that
the `s1` subtest actually incurs a fault on strict-alignment targets like
Sparc which UBSan doesn't expect.
This can be fixed like the `w1` subtest by compiling with
`-fno-sanitize-recover=alignment`.
Tested on `sparcv9-sun-solaris2.11`, `amd64-pc-solaris2.11`, and
`x86_64-pc-linux-gnu`.

The entries in VectorizableTree are not necessarily ordered by their
position in basic blocks. Collect them and order them by dominance so
later instructions are guaranteed to be visited first. For instructions
in different basic blocks, we only scan to the beginning of the block,
so their order does not matter, as long as all instructions in a basic
block are grouped together. Using dominance ensures a deterministic order.
The modified test case contains an example where we compute a wrong
spill cost (2) without this patch, even though there is no call between
any instruction in the bundle.
This seems to have limited practical impact, .e.g on X86 with a recent
Intel Xeon CPU with -O3 -march=native -flto on MultiSource,SPEC2000,SPEC2006
there are no binary changes.

SCEVExpander already tracks which instructions have been inserted n
InsertedValues/InsertedPostIncValues. This patch adds an additional
vector to collect the instructions in insertion order. This can then be
used to remove exactly the instructions inserted by the expander.
This replaces ExpandedValuesCleaner, which in some cases might remove
values not inserted by the expander (e.g. if a value was dead before
insertion and is then used during expansion).

We skip debug instructions in RDA so we cannot attempt to look them
up in our instruction map without causing a crash. But some of the
methods select the last instruction in the block and this
instruction may be a debug instruction... So, use getLastNonDebugInstr
instead of calling back on a MachineBasicBlock.
MachineBasicBlock iterators have also been updated to use
instructionsWithoutDebug so we can avoid the manual checks for debug
instructions.
