Reapply [InstCombine] Switch foldOpIntoPhi() to use InstSimplify

Relative to the previous attempt, this is rebased over the
InstSimplify fix in ac74e7a7806480a000c9a3502405c3dedd8810de,
which addresses the miscompile reported in PR58401.

-----

foldOpIntoPhi() currently only folds operations into the phi if all
but one operands constant-fold. The two exceptions to this are freeze
and select, where we allow more general simplification.

This patch makes foldOpIntoPhi() generally simplification based and
removes all the instruction-specific logic. We just try to simplify
the instruction for each operand, and for the (potentially) one
non-simplified operand, we move it into the new block with adjusted
operands.

This fixes https://github.com/llvm/llvm-project/issues/57448, which
was my original motivation for the change.

InstSimplify currently checks whether the instruction simplifies

should only occur in unreachable code.

However, this was also done for the simplifyInstructionWithOperands()
API. In that case, the instruction only serves as a template that
provides the opcode and other non-operand data. In this case,
simplifying back to the same "instruction" may be expected. This
caused PR58401 in conjunction with D134954.

As such, move this check into simplifyInstruction() only. The only
other caller of simplifyInstructionWithOperands() also handles the
self-simplification case explicitly.

years, so it has been exposed to quite some code. Then around the time

MemorySSA state and we moved it to a loop pass manager, which both

[demangler] Simplify OutputBuffer initialization

Every non-testcase use of OutputBuffer contains code to allocate an
initial buffer (using either 128 or 1024 as initial guesses). There's
now no need to do that, given recent changes to the buffer extension
heuristics -- it allocates a 1k(ish) buffer on first need.

Just pass in a buffer (if any) to the constructor.  Thus the
OutputBuffer's ownership of the buffer starts at its own lifetime
start. We can reduce the lifetime of this object in several cases.

That new constructor takes a 'size_t *' for the size argument, as all
uses with a non-null buffer are passing through a malloc'd buffer from
their own caller in this manner.

The buffer reset member function is never used, and is deleted.

Some adjustment to a couple of uses is needed, due to the lazy buffer
creation of this patch.

a) the Microsoft demangler can demangle empty strings to nothing,
which it then memoizes.  We need to avoid the UB of passing nullptr to
memcpy.

b) a unit test checks insertion of no characters into an empty buffer.
We need to avoid UB when converting that to std::string.

The original buffer initialization code would return a failure code if
that first malloc failed.  Existing code either ignored that, called
std::terminate with a FIXME, or returned an error code.

But that's not foolproof anyway, as a subsequent buffer extension
failure ends up calling std::terminate. I am working on addressing
that unfortunate failure mode in a manner more consistent with the C++
ABI design.

If the divisor is a power-of-2 or negative-power-of-2 and the dividend
is known to have >= trailing zeros than the divisor, the division is exact:
https://alive2.llvm.org/ce/z/UGBksM (general proof)

This isn't the most direct optimization (we could create ashr in these

[llvm-objdump/mac] Add new function starts print mode

This updates the `--function-starts` argument to now accept 3 different
modes, `addrs` for just printing the addresses of the function starts
(previous behavior), `names` for just printing the names of the function
starts, and `both` to print them both side by side.

In general if you're debugging function starts issues it's useful to see
the symbol name alongside the address. This also mirrors Apple's
`dyldinfo -function_starts` command which prints both.
