Explanation: Use the new space-separated format for the
-fdepscan-prefix-mapflag when calling LLVM from Swift, as well as using the new API used to implement that option which usesstd::pairinstead of single strings.Scope: This should not cause any backward compatibility issues since it is not changing any option for Swift itself, it is just adjusting it to use the new option introduced in swiftlang/llvm-project#10740.
Issues: rdar://129434789
Original PRs: #81792
Risk: Low, does not change Swift's API or CLI flags.
Testing: The new functionality is implemented and tested in the corresponding LLVM PR swiftlang/llvm-project#10740, there are no tests added in this PR.
