[lldb] Don't resolve dynamic type info if no named type exists (#214828)

Intends to fix the failure from
https://github.com/llvm/llvm-project/pull/212013#issuecomment-5220617065.

I overlooked that the original code returned an empty `TypeAndOrName` if
no type with the specified name was found:

In my PR, I always returned a `TypeAndOrName` with a name set. With this
change, we only set return a non-empty `TypeAndOrName` if there was any
type with the specified name.

[mlir][llvm] support DICompileUnit source language dialect (#214301)

## Summary

LLVM IR `DICompileUnit` supports an optional `dialect:` field as part of
its `DISourceLanguageName`, for example:

```
!0 = distinct !DICompileUnit(
  language: DW_LANG_C,
  file: !1,
  dialect: DW_LLVM_LANG_DIALECT_simt
)
```

The MLIR LLVM dialect previously modeled only the base `sourceLanguage`,
so LLVM IR import dropped the dialect and MLIR-to-LLVMIR export could
not emit it.

[DebugInfo] Keep validating after register and entry-value ops (#214057)

isValid returned as soon as it saw a compact DW_OP_regN or DW_OP_bregN
operation, or a valid DW_OP_LLVM_entry_value. Operations after that
point skipped the remaining checks.

Let's keep walking the expression. DW_OP_regx and DW_OP_bregx already
leave the switch and continue validating the expression, so this makes
the compact forms validate their suffixes too. Entry-value suffixes are
also intentional here.

This adds no register-specific suffix rule. DWARF 5 requires a register
location to stand alone as an entire object or piece, while accepted
DWARF issue 230524.1 permits a register location followed by a
dereference in DWARF 6. Since isValid() does not know the emitted DWARF
version, we keep it limited to applying its existing checks to the
suffix.

Test each early-return path with a different invalid suffix: a stack
