  [NFC][mlir][spirv] Fix syntax warnings in gen_spirv_dialect.py (#111775)

In the context of regular expressions, Python (used to) gracefully
ignore the escape behavior of `\` in some contexts, e.g. for
representing the regular expression `\w+`. However in newer versions of
Python this now gives a warning in the form

```
SyntaxWarning: invalid escape sequence '\w'
```

Fix by explicitly using raw strings instead.

  [CodeGenPrepare] Convert `ctpop(X) ==/!= 1` into `ctpop(X) u</u> 2/1` (#111284)

Some targets have better codegen for `ctpop(X) u< 2` than `ctpop(X) ==
1`. After https://github.com/llvm/llvm-project/pull/100899, we set the
range of ctpop's return value to indicate the argument/result is
non-zero.

This patch converts `ctpop(X) ==/!= 1` into `ctpop(X) u</u> 2/1` in CGP
to fix https://github.com/llvm/llvm-project/issues/95255.

  [lldb-dap] Implement value locations for function pointers (#104589)

This commit adds `valueLocationReference` to function pointers and
function references. Thereby, users can navigate directly to the
pointed-to function from within the "variables" pane.

In general, it would be useful to also a add similar location references
also to member function pointers, `std::source_location`,
`std::function`, and many more. Doing so would require extending the
formatters to provide such a source code location.

There were two RFCs about this a while ago:

https://discourse.llvm.org/t/rfc-extending-formatters-with-a-source-code-reference/68375
https://discourse.llvm.org/t/rfc-sbvalue-metadata-provider/68377/26

However, both RFCs ended without a conclusion. As such, this commit now
implements the lowest-hanging fruit, i.e. function pointers. If people
find it useful, I will revive the RFC afterwards.

X86 maxss/minss etc. instructions won't turn SNaN to QNaN, so we can
combine fcmp + select to them for some predicates.

  [Clang] Instantiate Typedefs referenced by type alias deduction guides (#111804)

TypedefNameDecl referenced by a synthesized CTAD guide for type aliases
was not transformed previously, resulting in a substitution failure in
BuildDeductionGuideForTypeAlias() when substituting into the
right-hand-side deduction guide.

This patch fixes it in the way we have been doing since
https://reviews.llvm.org/D80743. We transform all the function
parameters, parenting referenced TypedefNameDecls with the
CXXDeductionGuideDecl. Then we instantiate these declarations in
FindInstantiatedDecl() as we build up the eventual deduction guide,
using the mechanism introduced in D80743

Fixes #111508
