Reverts #68558

This PR is causing 23 new Swift test failures on rebranch on macOS.
https://ci.swift.org/view/Swift%20rebranch/job/oss-swift-rebranch-incremental-RA-macos/2718/

The only compiler-related change in this build job was e06ba23

The testing on the related PR was from too long ago to see the results, but macOS should be testing green on rebranch.

@swift-ci please test

[etcwilde]

macOS failure:

Failed Tests (1):
  lldb-api :: lang/swift/variables/consume_operator/TestSwiftConsumeOperator.py

@adrian-prantl, I could have sworn that test was disabled, or was it re-enabled?
Looks like @felipepiovezan re-enabled it apple/llvm-project#7497

[adrian-prantl]

Maybe the test is flaky?

[felipepiovezan]

I have disabled it again, it was an ARM vs X86 thing, which is why it passes locally but not on the bots
