Instead of checking '!Zfh && Zhfmin' first, handle Zfh. Then assert
that the other case is F+Zfhmin. The F+Zfhmin check will need to be
relaxed for bfloat16 support. As it was written before there would
be now error to catch that. Instead it would just silently create
fsgnj.h instructions.

An in-flight materialization may try to claim responsibility for new symbols
(via MaterializationResponsibility::defineMaterializing) after the tracker that
is associated with the materialization is removed, leaving the tracker defunct.

Failure to error out early here could leave the JITDylib in an invalid state,
with defineMaterializing associating new symbols with the already-defunct
tracker. Erroring out early prevents this.

Follow-up to D155123, uniformly handle cases where there are duplicate
-mios-verion-min arguments.

This placeholder is only used during the execution of the algorithm, and it's patched with a
concrete value at the end

It was using undef as placeholder for getting the TTI cost for cttz
While at it, update the comments about cttz's last argument (is_zero_poison)

This allows us to remove some curly braces around the if body.
The code wasn't consistent about it anyway. Comments before is
used in other places in this file already.

We can use a null SDValue for the 'false' case. This avoids the

Avoids some code duplication.

In https://reviews.llvm.org/D126664, a warning is introduced
warning against the deprecated out of line definition of a
static constexpr member in C++17 and later. Prior to this patch,
the only diagnostic group controlling this diagnostic was -Wdeprecated,
which controls many many diagnostics. This patch creates
a diagnostic group specifically for this warning so it can
be controlled in isolation, while also being included with -Wdeprecated.

This keeps all the scalar code together.

This patch implements a new inlay hint feature proposed in https://github.com/clangd/clangd/issues/1634. It introduces a new inlay hint kind BlockEnd which shows a comment-like hint after a definition brace pair, including function/type/namespace. For example,
```
void foo() {
} ^
```
In the code shown above, a hint should be displayed at ^ labelling `// foo`. Such hint only shows when there's no trailing character after the position except whitespaces and optionally ';'.

Also, new configurations are introduced in the inlay hints block
```
InlayHints:
    BlockEnd: Yes # toggling the feature
```

GNU ld added ^ support in July 2023 and it looks like ^= is in plan as

For now, we don't support `a^=0` (^= without a preceding space).

When generating XCOFF, the compiler generates a csect with an internal
name.  Each function results in a label within the csect.  This patch
replaces the internal name ".text" with an empty string "".  This avoids
adding special code to handle a function text() in the source file, and
works better with some XCOFF tools that are confused when the csect and
the first function have the same address.

This patch adds a new option -fkeep-persistent-storage-variables to emit
