Issue Description:
When compiling swift-atomics (https://github.com/apple/swift-atomics) at commit ccce007 against the 2020-10-24 toolchain snapshot for macOS 10.15.7, compilation fails with the following output while compiling AtomicBool.swift:
Assertion failed: (castIsValid(op, S, Ty) && "Invalid cast!"), function Create, file /Users/buildnode/jenkins/workspace/oss-swift-package-osx/llvm-project/llvm/lib/IR/Instructions.cpp, line 2873.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.
