[lldb] Upgrade GetIndexOfChildWithName to use llvm::Expected (#136693)
This patch replaces the use of `UINT32_MAX` as the error return value of
`GetIndexOfChildWithName` with `llvm::Expected`.


# Tasks to do in another PR

1. Replace `CalculateNumChildrenIgnoringErrors` with
`CalculateNumChildren`. See [this
comment](https://github.com/llvm/llvm-project/pull/136693#discussion_r2056319358).
2. Update `lldb_private::formatters::ExtractIndexFromString` to use
`llvm::Expected`. See [this
comment](https://github.com/llvm/llvm-project/pull/136693#discussion_r2054217536).
3. Create a new class which carries both user and internal errors. See
[this
comment](https://github.com/llvm/llvm-project/pull/136693#discussion_r2056439608).

[lldb] Upgrade CompilerType::GetBitSize to return llvm::Expected (#129601)
This patch pushes the error handling boundary for the GetBitSize()
methods from Runtime into the Type and CompilerType APIs. This makes it
easier to diagnose problems thanks to more meaningful error messages
being available. GetBitSize() is often the first thing LLDB asks about a
type, so this method is particularly important for a better user
experience.

[lldb][TypeSystemClang] Add support for floating point template argument constants (#127206)
This patch adds support for template arguments of
`clang::TemplateArgument::ArgKind::StructuralValue` kind (added in
https://github.com/llvm/llvm-project/pull/78041). These are used for
non-type template parameters such as floating point constants. When LLDB
created `clang::NonTypeTemplateParmDecl`s, it previously assumed
integral values, this patch accounts for structural values too.

Anywhere LLDB assumed a `DW_TAG_template_value_parameter` was
`Integral`, it will now also check for `StructuralValue`, and will
unpack the `TemplateArgument` value and type accordingly.

We can rely on the fact that any `TemplateArgument` of `StructuralValue`
kind that the `DWARFASTParserClang` creates will have a valid value,
because it gets those from `DW_AT_const_value`.

[lldb] Provide default impl for MightHaveChildren (NFC) (#119977)
The vast majority of `SyntheticChildrenFrontEnd` subclasses provide
children, and as such implement `MightHaveChildren` with a constant
value of `true`. This change makes `true` the default value. With this
change, `MightHaveChildren` only needs to be implemented by synthetic
providers that can return `false`, which is only 3 subclasses.

Change GetNumChildren()/CalculateNumChildren() methods return
llvm::Expected

This is an NFC change that does not yet add any error handling or change
any code to return any errors.

This is the second big change in the patch series started with
https://github.com/llvm/llvm-project/pull/83501

A follow-up PR will wire up error handling.

14d95b26ae [lldb][NFCI] Remove unneeded ConstString conversions
ConstString can be implicitly converted into a llvm::StringRef. This is
very useful in many places, but it also hides places where we are
creating a ConstString only to use it as a StringRef for the entire
lifespan of the ConstString object.

I locally removed the implicit conversion and found some of the places we
were doing this.

a1a74f7cde [lldb] Default can_create to true in GetChildAtIndex (NFC)
Existing callers of `GetChildAtIndex` pass true for can_create. This change
makes true the default value, callers don't have to pass an opaque true.

See also D151966 for the same change to `GetChildMemberWithName`.

2fe8327406 [lldb] Use std::optional instead of llvm::Optional (NFC)
This patch replaces (llvm::|)Optional< with std::optional<.  I'll post
a separate patch to clean up the "using" declarations, #include
"llvm/ADT/Optional.h", etc.

This is part of an effort to migrate from llvm::Optional to
std::optional:
