blocks:

  • SR-10294 convertBoolToDarwinBool and friends should be inlined

Issue Description:

If you apply the attached standard library patch, the compiler will crash (I believe when trying to emit debug info)

Search for 'UNREACHABLE executed at /Users/buildnode/jenkins/workspace/swift-PR-osx-smoke-test/branch-master/swift/lib/SIL/SILLocation.cpp:220!' in the build log

Causing this to happen should be as simple as calling any bridged function that takes a BOOL or Boolean argument, e.g.

(NSNumber(true)).boolValue

and compiling with debug info
