601583e5a3 [lldb/Utility] Fix layering violation caused by ScriptedMetadata
This patch moves `ScriptedMetadata.h` from the `Interpreter` directory to
the `Utility` sub-directory since `ProcessInfo.h` depends on it.

It also gets rid of the unused `OptionGroupPythonClassWithDict`
constructor for `ScriptedMetadata` which would address the layering
violation.

b9d4c94a60 [lldb/Plugins] Add Attach capabilities to ScriptedProcess
This patch adds process attach capabilities to the ScriptedProcess
plugin. This doesn't really expects a PID or process name, since the
process state is already script, however, this allows to create a
scripted process without requiring to have an executuble in the target.

In order to do so, this patch also turns the scripted process related
getters and setters from the `ProcessLaunchInfo` and
`ProcessAttachInfo` classes to a `ScriptedMetadata` instance and moves
it in the `ProcessInfo` class, so it can be accessed interchangeably.

This also adds the necessary SWIG wrappers to convert the internal
`Process{Attach,Launch}InfoSP` into a `SB{Attach,Launch}Info` to pass it
as argument the scripted process python implementation and convert it
back to the internal representation.

2f88c07cf8 [lldb] StructuredData should not truncate uint64_t values
In json::Value, getAsInteger returns an optional<int64_t> and getAsNumber
returns an optional<double>. If a value is larger than what an int64_t
can hold but smaller than what a uint64_t can hold, the getAsInteger
function will fail but the getAsNumber will succeed. However, the value
shouldn't be interpreted as a double.

1d7961fd1a [LLDB][RISCV] Add RVV registers enums
RVV stands for "RISC-V V Extension", which adds 32 vector registers, and seven unprivileged CSRs (vstart, vxsat, vxrm, vcsr, vtype, vl, vlenb) to a base scalar RISC-V ISA.

The base vector extension is intended to provide general support for data-parallel execution within the 32-bit instruction encoding space, with later vector extensions supporting richer functionality for certain domains.

b1f4f06ded [LLDB][LoongArch] Delete the s9 register alias definition
In RegisterInfos_loongarch64.h, r22 is defined twice. Having an extra array

f09cf34d00 [Support] Move TargetParsers to new component
This is a fairly large changeset, but it can be broken into a few
pieces:
- `llvm/Support/*TargetParser*` are all moved from the LLVM Support
  component into a new LLVM Component called "TargetParser". This
  potentially enables using tablegen to maintain this information, as
  is shown in https://reviews.llvm.org/D137517. This cannot currently
  be done, as llvm-tblgen relies on LLVM's Support component.
- This also moves two files from Support which use and depend on
  information in the TargetParser:
  - `llvm/Support/Host.{h,cpp}` which contains functions for inspecting
    the current Host machine for info about it, primarily to support
    getting the host triple, but also for `-mcpu=native` support in e.g.
    Clang. This is fairly tightly intertwined with the information in
    `X86TargetParser.h`, so keeping them in the same component makes
    sense.
  - `llvm/ADT/Triple.h` and `llvm/Support/Triple.cpp`, which contains
    the target triple parser and representation. This is very intertwined
    with the Arm target parser, because the arm architecture version
    appears in canonical triples on arm platforms.
- I moved the relevant unittests to their own directory.

And so, we end up with a single component that has all the information
about the following, which to me seems like a unified component:
- Triples that LLVM Knows about
- Architecture names and CPUs that LLVM knows about
- CPU detection logic for LLVM

Given this, I have also moved `RISCVISAInfo.h` into this component, as
it seems to me to be part of that same set of functionality.

If you get link errors in your components after this patch, you likely
need to add TargetParser into LLVM_LINK_COMPONENTS in CMake.

Different parts of LLDB can register callbacks (this is necessary for
layering purposes) that will get called when the diagnostics should be

I had incorrectly removed one set of checks in the option handling in

bit obscure, but it handled the case where you pass "-something=other --"
as the input_line, which caused the built-in "run" alias not to return

This was causing the test test_help_run_hides_options from TestHelp.py to
fail on Linux and Windows (but the test succeeds on macOS).  The decision
to print option information is determined by CommandObjectAlias::IsDashDashCommand
which was changed, but only by replacing an inline string constant with a const char *
CommandInterpreter::g_argument which has the same string value.  I can't see why this
would fail, I'll have to spin up a vm to see if I can repo there.

318454a8e5 Inline my uuid_is_null() implementation in a header file
This either needs to be static, or forced inline, or in a separate
source file.  Given that we only have one function in this
UuidCompatibility.h, I think forced inline for the handful of uses
of it may be best.

96d12187b3 Allow firmware binaries to be specified only by load address
Add support to Mach-O corefiles and to live gdb remote serial protocol
connections for the corefile/remote stub to provide a list of load
addresses of binaries that should be found & loaded by lldb, and nothing
else.  lldb will try to parse the binary out of memory, and if it can
find a UUID, try to find a binary & its debug information based on the
UUID, falling back to using the memory image if it must.

A bit of code unification from three parts of lldb that were loading
individual binaries already, so there is a shared method in
DynamicLoader to handle all of the variations they were doing.

Re-landing this with a uuid_is_null() implementation added to
Utility/UuidCompatibility.h for non-Darwin systems.
