[clang] Drop stale *-buildattr module flag emission (#211021)
Module flags `sign-return-address-buildattr` and
`tag-stack-memory-buildattr` are never exercised elsewhere by existing
tests or code across the whole LLVM source tree, and there are no known
cases of them being used.

Moreover, the `sign-return-address-buildattr` flag emission was gated by
`ptrauth` target feature which does not actually exist: see
`AArch64TargetInfo::computeFeatureLookup()` and
`ARMTargetInfo::hasFeature(StringRef Feature)`. So, it was never
emitted.

This patch removes code responsible for these stale module flags
emission.

Note: the flags was previously introduced in
https://reviews.llvm.org/D112421

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
