Issue Description:

The Swift trunk snapshot for March 14, 2018 crashes while compiling a 3rd party library we use: Charts v3.0.5.

Assertion failed: (T && "Expected non-null type!"), function setType, file /Users/buildnode/jenkins/workspace/oss-swift-package-osx/swift/lib/Sema/ConstraintSystem.h, line 1591.

If I'm reading the assertion failure correctly, it happened in CombinedChartView.swift, line 166/168

Attached is the "All Issues" output from Xcode, showing the assertion failure and the command that caused it, among other things

Maybe I put too many details into the Environment? Has toolchain, xcode version, OS version, project + target that crashes

Probably a 4.1 regression but not for sure, because Xcode compilers have asserts off. Thanks, Dan!

@e28eta, this only fails when using the trunk snapshot, correct, not with the Xcode 9.3 beta?

@rudkx, that's correct. With the toolchain included in 9.3b4 (9Q127n), the project compiles. It also compiles with the 4.1 snapshot (swift-4.1-DEVELOPMENT-SNAPSHOT-2018-03-14-a) that I downloaded last week.

The only one that does crash is the trunk snapshot.

Thanks!
