[llvm-extract] support unnamed bbs. (#135140)

Dear developer:

I have recently working with LLVM IR and I want to isolate basic blocks
using the command "llvm-extract". However, I found that the command
option "llvm-extract --bb func_name:bb_name" will only function when
dumping source code into IRs with options "-fno-discard-value-names".
That is to say, the "llvm-extract" command cannot support unnamed basic
blocks, which is a default output of the compiler. So, I made these
changes and hope they will make LLVM better.

Best regards,

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
