[ELF] Check COMMON symbols for PROVIDE and don't redefine COMMON symbols edata/end/etext
In GNU ld, the definition precedence is: regular symbol assignment > relocatable object definition > `PROVIDE` symbol assignment.
GNU ld's internal linker scripts define the non-reserved (by C and C++)
edata/end/etext with `PROVIDE` so the relocatable object definition takes
precedence. This makes sense because `int end;` is valid.
We currently redefine such symbols if they are COMMON, but not if they are

Fix this (also improve consistency and match GNU ld) by using the

[DAG] try to convert multiply to shift via demanded bits
This is a fix for a regression discussed in:
https://github.com/llvm/llvm-project/issues/53829
We cleared more high multiplier bits with 995d400,
but that can lead to worse codegen because we would fail
to recognize the now disguised multiplication by neg-power-of-2
as a shift-left. The problem exists independently of the IR
change in the case that the multiply already had cleared high
bits. We also convert shl+sub into mul+add in instcombine's
negator.
This patch fills in the high-bits to see the shift transform
opportunity. Alive2 attempt to show correctness:
https://alive2.llvm.org/ce/z/GgSKVX
The AArch64, RISCV, and MIPS diffs look like clear wins. The
x86 code requires an extra move register in the minimal examples,
but it's still an improvement to get rid of the multiply on all
CPUs that I am aware of (because multiply is never as fast as a
shift).
There's a potential follow-up noted by the TODO comment. We
should already convert that pattern into shl+add in IR, so
it's probably not common:

This cap was first added in

0539a26d.
In the meantime, the code has rotten fairly badly. Some intermediate refactoring caused the size to only be incremented if *both* iterators advance in the window search. This causes the size to be badly undercounted when near one end of a basic block. We no longer have any test which exercises the logic in an intentional way; there's one test which differs with this change, but the changes appear fairly orthoganol to the purpose of the test file.
Unfortunately, we no longer have the original motivating example, so it's possible that it also hits some other issue. I tested locally with a large example, but even at it's worst, that one doesn't demonstrate anything too extreme even without the algorithmic fix. It's clearly faster with, but only by ~20% which doesn't seem in line with the original commit message.

[clang][deps] Return the whole TU command line
The dependency scanner already generates canonical -cc1 command lines that can be used to compile discovered modular dependencies.
For translation unit command lines, the scanner only generates additional driver arguments the build system is expected to append to the original command line.
While this works most of the time, there are situations where that's not the case. For example with `-Wunused-command-line-argument`, Clang will complain about the `-fmodules-cache-path=` argument that's not being used in explicit modular builds. Combine that with `-Werror` and the build outright fails.

This can be extended within InstSimplify to handle cases where we 'and'

are inverted, but I think it's better to canonicalize that instead to

[RISCV] Avoid infinite loop between DAGCombiner::visitMUL and RISCVISelLowering::transformAddImmMulImm
See https://github.com/llvm/llvm-project/issues/53831 for a full discussion.
The basic issue is that DAGCombiner::visitMUL and
RISCVISelLowering;:transformAddImmMullImm get stuck in a loop, as the
current checks in transformAddImmMulImm aren't sufficient to avoid all
cases where DAGCombiner::isMulAddWithConstProfitable might trigger a
transformation. This patch makes transformAddImmMulImm bail out if C0

[Modules] Add module structure output to -module-file-info.
It is useful to be able to visualise the C++20 modules content of a PCM file
both for inspection and for testing. In particular, when adding more module
types to support C++20 Partitions and Header Units, we would like to be able
to confirm that the output PCM has the intended structure.
The existing scheme for dumping data is restricted to the content of the AST
file control block, which does not include structural data beyond imports.
The change here makes use of the AST unit that is set up by BeginSourceFile
to query for the information on the primary and sub-modules. We can then
inspect each of these in turn, accounting for Global, Private, Imported and
Exported modules/fragments and then showing the sub-stucture of the main
module(s).
The disadvantage of this mechanism is that it has no easy method to control
the granularity of the output. Perhaps more detailed inspection would be
better handled by a stand-alone module inspection tool.

[flang][driver] Make `flang-new` always generate run-time type info
Currently, the driver generates the tables with "run-time type
information for derived types" only when specific actions are run.
However, the corresponding data might be required by the subsequent
compilation stages (e.g. lowering, code-gen) and should be generated
unconditionally. Note that this is only possible once the semantic
checks have been run.
Note that when generating these tables, extra semantic errors might be
generated. The driver will always report these and in most cases such
semantic errors will cause the driver to exit immediately. The only
exception are actions inheriting from `PrescanAndSemaDebugAction`.
Currently, there's only one such action: `DebugDumpAllAction`
(corresponds to `-fdebug-dump-all` command-line flag). I've updated the
comments for this action to clarify this.
This change will mostly affect lowering, which currently is only
available for most basic examples (e.g. empty programs). I wasn't able
to find a working case that would demonstrate the new behaviour. I
hope that this change is straightforward enough and am submitting it
without a test.
