[DirectX] Fix resource binding analysis incorrectly removing duplicates (#152253)

The resource binding analysis was incorrectly reducing the size of the
`Bindings` vector by one element after sorting and de-duplication. This
led to an inaccurate setting of the `HasOverlappingBinding` flag in the
`DXILResourceBindingInfo` analysis, as the truncated vector no longer
reflected the true binding state.

This update corrects the shrink logic and introduces an `assert` in the
`DXILPostOptimizationValidation` pass. The assertion will trigger if
`HasOverlappingBinding` is set but no corresponding error is detected,
helping catch future inconsistencies.

The bug surfaced when the `srv_metadata.hlsl` and `uav_metadata.hlsl`
tests were updated to include unbounded resource arrays as part of
https://github.com/llvm/llvm-project/issues/145422. These updated test
files are included in this PR, as they would cause the new assertion to
fire if the original issue remained unresolved.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.
