Triple: Add BridgeOS to isOSDarwin (#145636)

This fixes a TODO and avoids a special case. Also required
hacking up a few cases to avoid asserting in codegen; it's not
confidence inspiring that there is only one codegen test using
a bridgeos triple and its specifically for the exp10 libcall
names.

This also changes the behavior, losing an extra leading _ in the
emitted name matching the other apple outputs. I have no idea if
this is right or not. IMO it's someone from apple's problem to fix
it and add appropriate test coverage, or we can rip all references
to BridgeOS out from upstream.

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.
