Swift-driver nightly on https://swift.godbolt.org/

Hi Folks,

Looks like swift-driver is turned on by default on nightly and Compiler Explorer (godbolt.org) is having issues. Anybody know how to bypass swift-driver via a flag? Perhaps you have bandwidth to help fix the config ? See issue below.

[BUG] Swift nightly doesn't compile · Issue #2692 · compiler-explorer/compiler-explorer (github.com)

-disallow-use-new-driver should bypass the error, at least.

Adopting swift-driver as default introduced a dependency on ncurses via LLBuild here:

// FIXME: Conditionalize these flags since SwiftPM 5.3 and earlier will crash for platforms they don't know about.
          #if os(Windows)
          
          
do {
              let llvmTargets: Set<String> = [
                  "llvmDemangle",
                  "llvmSupport",
          
          
        "llbuild",
                  "llbuildBasic",
                  "llbuildBuildSystem",
                  "llbuildCommands",
                  "llbuildNinja",
          
          
        "llbuildBasicTests",
                  "llbuildBuildSystemTests",
                  "llbuildCoreTests",
          
          
        "swift-build-tool",
              ]

The compiler explorer bot needs to be updated to contain this library.
