[orc-rt] Add multi-addr dealloc/release to SimpleNativeMemoryMap. (#163025)

In an ORC JIT it's common for multiple memory regions to be deallocated
at once, e.g. when a ResourceTracker covering multiple object files is
removed. This commit adds SimpleNativeMemoryMap::deallocateMultiple and
SimpleNativeMemoryMap::releaseMultiple APIs that can be used to reduce
the number of calls (and consequently IPC messages in cross-process
setups) in these cases.

Adding these operations will make it easier to write an
llvm::orc::MemoryMapper class that can use SimpleNativeMemoryMap as a
backend.

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.
