Issue Description:

Using Swift 5.5 DEVELOPMENT-SNAPSHOT-2021-07-08-a and a class with a trivial initializer marked async, swift fails with an assertion when -enable-testing is passed to the compiler:

Assertion failed: (!isa<ConstructorDecl>(decl)), function appendEntity, file /Users/buildnode/jenkins/workspace/oss-swift-5.5-package-macos/swift/lib/AST/ASTMangler.cpp, line 3004.

A seemingly-valid .o file is generated if the "-enable-testing" is removed from the compiler invocation.

Comment by Kit Transue (JIRA)

Discovered while attempting to reproduce with the 2021-07-17 toolchain:

The crash in 2021-07-08 is also squelched by '-validate-tbd-against-ir=none'.

(Note that with the newer swift-5.5-DEVELOPMENT-SNAPSHOT-2021-07-17-a toolchain, this option is newly-needed to get past widespread 'is in generated IR file, but not in TBD file' errors. Because of the -validate-tbd-against-ir=none workaround, this toolchain is unsuitable for reproducing this error.)
