[X86] combineX86ShuffleChainWithExtract - refactor to remove need to widen all vectors
combineX86ShuffleChain no longer needs the candidate shuffle inputs to all have been widened to root size, but combineX86ShuffleChainWithExtract still assumes that they have.
This refactor peeks through all inputs' extract_subvector nodes to find the widest legal vector type and widens the shuffle mask accordingly - it no longer bails if any of the inputs can't be widened to the new width.
combineX86ShuffleChainWithExtract now follows a similar process to combineX86ShufflesRecursively, so I think we should eventually be able to get rid of it and just let combineX86ShufflesRecursively handle widening the shuffle width as well.

This allows discouraging the use of specific build methods of an op by having TableGen generate C++ code, instructing the C++ compiler to warn on use of the `build` method.
The implementation uses the C++14 `[[deprecated(...)]]`` for this purpose. I considered using `LLVM_DEPRECATED`, but thought requiring a fix-it was not necassery, nor would the syntax in ODS have been very nice.
My motivation for this change is that in the future I'd like to deprecate the use `build` methods in the LLVM Dialect, not using explicit pointer types for ops such as `llvm.load` or `llvm.alloca`, which makes the code not future proof for opaque pointers. In-tree has to be clean first before I could commit such a change of course, but I thought the initial infrastructure change could already be submitted.

builds PowerPC in LLVM_TARGETS_TO_BUILD.

%vf.part1 = mul i32 %vscale, 4
%gep = getelementptr ..., i32 %vf.part1
Which InstCombine then changes into:

%vf.part1 = mul i32 %vscale, 4
%vf.part1.zext = sext i32 %vf.part1 to i64

D143016 tried to remove these extends, but that only works when
the call to llvm.vscale.i32() has a single use. After doing any
kind of CSE on these calls the combine no longer kicks in.
It seems more sensible to ask DataLayout what type to use, rather
than relying on InstCombine to insert the extend and hoping it can
fold it away.
I've only changed this for indices that are not constant, because
I vaguely remember there was a reason for sticking with i32. It

[flang][NFC] addSymbol/lookupSymbol clean-up
HLFIR requires mapping symbol to a single mlir::Value (produced
by a fir::FortranVariableOpInterface), while the current lowering
maps the value to a fir::ExtdendedValue.
So far, the HLFIR symbol query was a special one. Hence, all the code
directly using symMap.lookupSymbol and symMap.addSymbol did not work
with the lowering to HLFIR.
Refactor the code so that symbol lookup and add symbol go through
the converter in a centralize place that handles the HLFIR case
(translate fir::FortranVariableOpInterface to fir::ExtdendedValue
in lookups, and generate hlfir.declare when adding symbols).
In the refactoring, fir::FortranVariableOpInterface is added as
a symbolBox variant to avoid special casing all lookups (shallowLookup...).
Remove some unused SymbolBox member function instead of updating
them.

[C++20] [Modules] Allow ADL in dependent context for modules
Close https://github.com/llvm/llvm-project/issues/60488.
Previously, when we instantiate a template, the argument dependent
lookup is performed in the context of the instantiation, which implies that the
functions not visible in the context can't be found by the argument
dependent lookup.
But this is not true, according to [module.context]p3, the instantiation
context for the implicit instantiation of a template should contain the
context of the primary module interface if the template is defined in
the module interface unit.
Note that the fix didn't implemnet [module.context]p3 precisely, see the
comments for example.

In IR files, the attributes are only set for function while not the whole compile units.
So we extract the attributes from the first function and use it for the whole unit.
