Issue Description:

Facing the following error at step "--- Installing swiftpm --" while building Apple Swift 5 toolchain on PowerPC64LE using the master branch:

swift: /home/sar/swift-source/llvm/lib/Target/PowerPC/PPCISelLowering.cpp:12111: llvm::SDValue combineBVOfConsecutiveLoads(llvm::SDNode *, llvm::SelectionDAG &): Assertion `!(InputsAreConsecutiveLoads && InputsAreReverseConsecutive) && "The loads cannot be both consecutive and reverse consecutive."' failed.

Following fix was applied in order to run the swiftpm test suite on PowerPC64LE:-

diff --git a/Tests/BuildTests/BuildPlanTests.swift b/Tests/BuildTests/BuildPlanTests.swift @@ -28,7 +28,7 @@ import PackageLoading - let defaultTargetTriple: String = "ppc64le-unknown-linux" + let defaultTargetTriple: String = "powerpc64le-unknown-linux"

The detailed failure log is as under:-
