[analyzer] Eliminate unique release point assertion (#150240)

MallocChecker.cpp has a complex heuristic that supresses reports where
the memory release happens during the release of a reference-counted
object (to suppress a significant amount of false positives).

Previously this logic asserted that there is at most one release point
corresponding to a symbol, but it turns out that there is a rare corner
case where the symbol can be released, forgotten and then released
again. This commit removes that assertion to avoid the crash. (As this
issue just affects a bug suppression heuristic, I didn't want to dig
deeper and modify the way the state of the symbol is changed.)

Fixes #149754

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.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
