[LLVMABI] Add support for SVE types in the LLVM ABI library (#221375)
This change extends the LLVM ABI library's VectorType to be able to
describe SVE types and updates Clang's QualTypeMapper to map them.
The AArch64 target info class in the ABI library is still a work in
progress. It will continue to report "not yet implemented" for function
signatures involving SVE types. This change is a neceasary prerequisite
for correctly handling them or correctly deferring handling of these
specific types.

[lld][MachO] Add `--warn-missing-subsections-via-symbols` flag (#221464)
This change introduces:
* `--warn-missing-subsections-via-symbols`: Warns when an input object
file with non-empty sections is missing `MH_SUBSECTIONS_VIA_SYMBOLS`.
* `--no-warn-missing-subsections-via-symbols`: Disables the warning
(default).
Also adds documentation and lit tests.
Object files missing `MH_SUBSECTIONS_VIA_SYMBOLS` can prevent
dead-stripping and subsection splitting.
We have seen a number of cases where we are compiling assembly, and this
allows us to track them down.

[lldb][Darwin] Don't mark threads as having hit bp if not (#222488)
When a multithreaded program stops exeuction with a mach exception on
more than one thread, if one of the threads is *at* a breakpoint site,
but hasn't *hit* the breakpoint yet, lldb was incorrectly stepping over
the breakpoint instruction when it resumed execution. This would result
in TestConcurrentManyBreakpoints reporting that a breakpoint hit on 100
threads was only hit 99 times, because one of the breakpoints was
silently stepped past without being counted.
The bug happened because on Darwin/debugserver systems the stop info
packet includes a `jstopinfo` which is a JSON dictionary of all threads
that have an exception. When `jstopinfo` is present, ProcessGDBRemote
was initializing any thread not included in `jstopinfo` as having an
empty StopInfo. It did this without checking if we are _at_ a breakpoint
site, and marking the thread as "Stopped at unexecuted breakpoint
instruction". Because the threads now had an empty StopInfo already, the
other places where we might check "if stopped at unexecuted breakpoint
instruction" were never executed.
I created a gdb_remote_client API test with a synthetic test case where
four threads stop at a breakpoint; three of them have hit the
breakpoint, one has not. And confirm that lldb only registers 3
breakpoint hits initially, and then the 4th as we resume. Debugging the
"99 breakpoints hit instead of 100" failures was tricky and involved
running the test in a loop on a heavily loaded machine to get the
necessary timing, and it was easy to give up, so I wanted a much simpler
synthetic case to show the problem if we might regress.

Log Message:

[flang] Fold fir.convert of an integer constant between integer types (#222188)
`fir::ConvertOp::fold` doesn't handle an integer constant converted to
another integer type. `ForwardConstantConvertPattern` covers the
neighboring case where the result is `index`, so `fir.convert %c10_i32 :
(i32) -> index` already canonicalizes to an index constant while
`fir.convert %c1_i32 : (i32) -> i64` does not. This PR adds the
integer-to-integer case.
The width change follows the rules codegen applies to a non-constant
operand (`CodeGen.cpp`'s integer-to-integer conversion): narrowing
truncates, widening zero-extends an i1 or unsigned source and
sign-extends anything else. The result must be signless because the
constant materialises as an `arith.constant`, which only accepts
signless integers.
It composes with `arith::IndexCastOp::fold`, so a value widened then
cast to `index` collapses to one index constant, and it lets other
patterns see through the constant: with a literal shift,
`simplify-hlfir-intrinsics` can now fold away `hlfir.eoshift`'s
shift-direction arithmetic.
`getIntIfConstant` only matches `arith` and `llvm` constants, which are
signless, so `isUnsignedInteger()` is never true today, but I still kept
the unsigned case anyway so that the fold cannot disagree with codegen.
