[SelectionDAG] Use correct boolean representation in FoldConstantArithmetic
The description of SETCC says
/// SetCC operator - This evaluates to a true value iff the condition is

Without this patch, we sign extended the i1 to the used larger type

shown in the attached testcase that ended up returning -1 instead of
1 when using -mattr=+v.

[Flang] Initial lowering of the Fortran Do loop
This patch adds code to lower simple Fortran Do loops with loop control.
Lowering is performed by the the `genFIR` function when called with a
`Fortran::parser::DoConstruct`. `genFIR` function calls `genFIRIncrementLoopBegin`
then calls functions to lower the body of the loop and finally calls
the function `genFIRIncrementLoopEnd`. `genFIRIncrementLoopBegin` is
responsible for creating the FIR `do_loop` as well as storing the value of
the loop index to the loop variable. `genFIRIncrementLoopEnd` returns
the incremented value of the loop index and also stores the index value
outside the loop. This is important since the loop variable can be used
outside the loop. Information about a loop is collected in a structure
`IncrementLoopInfo`.
Note 1: Future patches will bring in lowering for unstructured,
infinite, while loops
Note 2: This patch is part of upstreaming code from the fir-dev branch of
https://github.com/flang-compiler/f18-llvm-project.

[AST] Improve traversal of concepts and concept requirements
- Do not traverse concept decl inside `AutoType`. We only traverse
declaration and definitions, not references to a declaration.
- Do not visit implicit AST node the relevant traversal mode.
- Add traversal extension points for concept requirements.
- Renamed `TraverseConceptReference` to mark as helper to share
the code. Having an extension point there seems confusing given that
there are many concept refences in the AST that do not call the
helper. Those are `AutoType`, `AutoTypeLoc` and constraint requirements.
Only clangd code requires an update.
There are no use-cases for concept requirement traversals yet, but
I added them in the earlier version of the patch and decided to keep
them for completeness.

[modules] Merge equivalent extensions and diagnose ivar redeclarations for extensions loaded from different modules.
Emitting metadata for the same ivar multiple times can lead to
miscompilations. Objective-C runtime adds offsets to calculate ivar
position in memory and presence of duplicate offsets causes wrong final
position thus overwriting unrelated memory.
Such a situation is impossible with modules disabled as clang diagnoses
ivar redeclarations during sema checks after parsing
(`Sema::ActOnFields`). Fix the case with modules enabled by checking
during deserialization if ivar is already declared. We also support
a use case where the same category ends up in multiple modules. We
don't want to treat this case as ivar redeclaration and instead merge
corresponding ivars.
