  [mlir][func] Fix a crash in DuplicateFunctionEliminationPass (#209667)

Previously, we used `SymbolUserMap::replaceAllUsesWith` to replace
symbols, but this could not update the symbol table cached by
`SymbolUserMap` during traversal, leading to a crash. This PR switches
to `SymbolTable::replaceAllSymbolUses`, which always operates on the
latest symbol table and avoids the crash. Fixes #209648.

  [libclc] Add initial support for libclc execution conformance tests (#214072)

Summary:
This uses the `llvm-gpu-loader` tool to invoke OpenCL test kernels. This
routes OpenCL through the standard compute runtimes, which aren't
exactly 1-to-1 with OpenCL, but it's close enough. Obviously, the best
solution would be to have a real OpenCL host library that can launch
these, but this is the best we can get in-tree and is very sipmle, write
kernel, test kernel.

The goal is to have a lot more tests run here, but this just gets the
basic infrastructure in place. We won't be able to do full conformance
like external suites, like exhaustive math, but I think its' a step in
the right direction. It looks like this on my side:

```console
$ ninja check-libclc-amdgpu-amd-amdhsa-llvm
```

This requires building with the LLVM `offload/` runtime enabled for the
source compiler.

  [flang][driver] Support Makefile dependency generation (#209379)

Implement the GCC/Clang dependency-file flags for flang, which it
previously rejected as unknown arguments: -M, -MM, -MD, -MMD, -MF,
-MT and -MQ.

Feature:
 -  -MD/-MMD : write a .d file alongside a normal compile
 -  -M/-MM   : run through semantics; emit deps to stdout by default
 -  -MF      : dependency-file path
 -  -MT/-MQ  : target name (verbatim / Make-quoted)
  (-M==-MM and -MD==-MMD; Fortran has no system/user header split.)

Design:
- `-M`/`-MM`: driver passes `-fsyntax-only -dependency-file - -MT
  <target>` to `-fc1`. Running through semantics resolves USE
  statements so module file dependencies are captured in the output.
  This deviates from clang's prescan-only behaviour for -M, but is
  intentional: unlike C/C++ #include, Fortran's USE statement is
  resolved at the semantic stage, not during preprocessing.

- `-MD`/`-MMD`: driver passes `-dependency-file foo.d -MT <target>`
  alongside the normal compile action. The object file is produced as
  usual, and the dependency file is written as a side effect.

- `-MF <path>` overrides where the dependency file is written.
  `-MT <target>` sets the target name (the part before the colon in
  the Make rule) verbatim. `-MQ` does the same but additionally
  quotes characters that are special to Make.

- In `-fc1`, `-dependency-file` and `-MT` are stored in the frontend
  options. After the action, `writeDependencyFile()` is called
  unconditionally. It collects every file opened during the action —
  the source plus all INCLUDE/#include/USE module files — via
  `GetIncludedFilePaths()`, then writes the
  `target: source includes...` Make rule to the specified file, or
  stdout if the path is `-`.
