[swiftc (136 vs. 5189)] Add crasher in swift::maybeAddAccessorsToVariable
Add test case for crash triggered in `swift::maybeAddAccessorsToVariable`.
Current number of unresolved compiler crashers: 136 (5189 resolved)
Assertion failure in [`lib/AST/Decl.cpp (line 3028)`](https://github.com/apple/swift/blob/master/lib/AST/Decl.cpp#L3028):
```
Assertion `getMutableAddressor()' failed.
When executing: bool swift::AbstractStorageDecl::isSetterNonMutating() const
```
Assertion context:
```
case AbstractStorageDecl::Addressed:
case AbstractStorageDecl::AddressedWithTrivialAccessors:
case AbstractStorageDecl::AddressedWithObservers:
case AbstractStorageDecl::ComputedWithMutableAddress:
assert(getMutableAddressor());
return !getMutableAddressor()->isMutating();
}
llvm_unreachable("bad storage kind");
}
```
