[clang][cli] Store additional optimization remarks info
After a revision of D96274 changed `DiagnosticOptions` to not store all remark arguments **as-written**, it is no longer possible to reconstruct the arguments accurately from the class.
This is caused by the fact that for `-Rpass=regexp` and friends, `DiagnosticOptions` store only the group name `pass` and not `regexp`. This is the same representation used for the plain `-Rpass` argument.
Note that each argument must be generated exactly once in `CompilerInvocation::generateCC1CommandLine`, otherwise each subsequent call would produce more arguments than the previous one. Currently this works out because of the way `RoundTrip` splits the responsibilities for certain arguments based on what arguments were queried during parsing. However, this invariant breaks when we move to single round-trip for the whole `CompilerInvocation`.
This patch ensures that for one `-Rpass=regexp` argument, we don't generate two arguments (`-Rpass` from `DiagnosticOptions` and `-Rpass=regexp` from `CodeGenOptions`) by shifting the responsibility for handling both cases to `CodeGenOptions`. To distinguish between the cases correctly, additional information is stored in `CodeGenOptions`.
The `CodeGenOptions` parser of `-Rpass[=regexp]` arguments also looks at `-Rno-pass` and `-R[no-]everything`, which is necessary for generating the correct argument regardless of the ordering of `CodeGenOptions`/`DiagnosticOptions` parsing/generation.

[Coroutine] Check indirect uses of alloca when checking lifetime info
In the existing logic, we look at the lifetime.start marker of each alloca, and check all uses of the alloca, to see if any pair of the lifetime marker and an use of alloca crosses suspension point.
This approach is unfortunately incorrect. An use of alloca does not need to be a direct use, but can be an indirect use through alias.
Only checking direct uses can miss cases where indirect uses are crossing suspension point.
This can be demonstrated in the newly added test case 007.
In the test case, both x and y are only directly used prior to suspend, but they are captured into an alias, merged through a PHINode (so they couldn't be materialized), and used after CoroSuspend.
If we only check whether the lifetime starts cross suspension points with direct uses, we will put the allocas to the stack, and then capture their addresses in the frame.
Instead of fixing it in D96441 and D96566, this patch takes a different approach which I think is better.
We still checks the lifetime info in the same way as before, but with two differences:
1. The collection of liftime.start is moved into AllocaUseVisitor to make the logic more concentrated.
2. When looking at lifetime.start and use pairs, we not only checks the direct uses as before, but in this patch we check all uses collected by AllocaUseVisitor, which would include all indirect uses through alias. This will make the analysis more accurate without throwing away the lifetime optimization.

[lldb] Support debugging utility functions
LLDB uses utility functions to run code in the inferior for its own
internal purposes, such as reading classes from the Objective-C runtime
for example. Because these expressions should be transparent to the
user, we ignore breakpoints and unwind the stack on errors, which
makes them hard to debug.
This patch adds a new setting target.debug-utility-expression that, when
enabled, changes these options to facilitate debugging. It enables
breakpoints, disables unwinding and writes out the utility function
source code to disk so it shows up in the source view.

[RISCV] Support fixed vector extract element. Use VL=1 for scalable vector extract element.
I've changed to use VL=1 for slidedown and shifts to avoid extra
element processing that we don't need.
The i64 fixed vector handling on i32 isn't great if the vector type
isn't legal due to an ordering issue in type legalization. If the
vector type isn't legal, we fall back to default legalization
which will bitcast the vector to vXi32 and use two independent extracts.
Doing better will require handling several different cases by
manually inserting insert_subvector/extract_subvector to adjust the type
to a legal vector before emitting custom nodes.

[lit] Add --ignore-fail
For some build configurations, `check-all` calls lit multiple times to
run multiple lit test suites. Most recently, I've found this to be
true when configuring openmp as part of `LLVM_ENABLE_RUNTIMES`, but
this is not the first time.
If one test suite fails, none of the remaining test suites run, so you
cannot determine if your patch has broken them. It can then be
frustrating to try to determine which `check-` targets will run the
remaining tests without getting stuck on the failing tests.
When such cases arise, it is probably best to adjust the cmake
configuration for `check-all` to run all test suites as part of one
lit invocation. Because that fix will likely not be implemented and
land immediately, this patch introduces `--ignore-fail` to serve as a
workaround for developers trying to see test results until it does
land:
```
$ LIT_OPTS=--ignore-fail ninja check-all
```
One problem with `--ignore-fail` is that it makes it challenging to
detect test failures in a script, perhaps in CI. This problem should
serve as motivation to actually fix the cmake configuration instead of
continuing to use `--ignore-fail` indefinitely.

This is still a different algorithm than what we do in LegalizeDAG

[AArch64] Do not fold SP adjustments into pre-increment addr modes if it overflows the redzone.
Instead of outright disabling this completely with the noredzone attribute,
we only avoid doing the optimization if there are memory operations between

This avoids the case of something like a stack cookie being corrupted if an
exception happens before the pre-increment to the SP occurs.
This also prevents the folding happening if we have a redzone, but the offset
being folded is above the redzone amount (128 bytes in this case).

This makes sure that images are loaded in the order in which they are registered with libomptarget.
If a target can load multiple images and these images depend on each other (for example if one image contains the programs target regions and one image contains library code), then the order in which images are loaded can be important for symbol resolution (for example, in the VE plugin).
In this case: because the same code exist in the host binaries, the order in which the host linker loads them (which is also the order in which images are registered with libomptarget) is the order in which the images have to be loaded onto the device.
