Batch mode in swift-driver passes wrong object name

[rjmansfield]

Description

Using -enable-batch-mode results in a link failure as wrong object file name is used.

Reproduction

$ swiftc -enable-batch-mode ~/hw.swift 
error: link command failed with exit code 1 (use -v to see invocation)
clang: error: no such file or directory: '/var/folders/cl/z48nl9xx18307rwb9l42n2yr0000gn/T/TemporaryDirectory.u1TWon/hw-1.o'
clang: error: no input files
error: fatalError

The frontend generates /var/folders/cl/z48nl9xx18307rwb9l42n2yr0000gn/T/TemporaryDirectory.IYWkMJ/hw-2.o but then tries to link /var/folders/cl/z48nl9xx18307rwb9l42n2yr0000gn/T/TemporaryDirectory.IYWkMJ/hw-1.o

Using the older driver works:

$ SWIFT_USE_OLD_DRIVER=1  SWIFT_EXEC=/Users/ryan_mansfield/swift/build/Ninja-RelWithDebInfoAssert/swiftdriver-macosx-arm64/arm64-apple-macosx10.15/release/bin/swiftc SWIFT_DRIVER_SWIFT_FRONTEND_EXEC=~/swift/build/Ninja-ReleaseAssert/swift-macosx-arm64/bin/swift-frontend swiftc -enable-batch-mode ~/hw.swift 
<unknown>:0: warning: legacy driver is now deprecated; consider avoiding specifying 'SWIFT_USE_OLD_DRIVER'
$ echo $?
0

Expected behavior

Link executable successfully.

Environment

Swift version 6.0-dev (LLVM 57177aa1b91540b, Swift 85c0555c89e568d)
