After failing compilation we proceed with jsii analysis, to give as much
information as possible in one go.
However, some compilation failures lead to a lack of information that
make the jsii analyzer crash, which ultimately leads jsii to fail with
no more information than:
Error: TypeError: Cannot read property 'getJsDocTags' of undefined
Fix this in two ways:
- First, detect the situation where this occurs and produce a more
useful error message.
- Guard against this happening in general by catching exceptions
during type analysis and still printing the compilation errors.

### Bug Fixes * **assembler:** handle unknown types without crashing ([#501](#501)) ([7ba1aab](7ba1aab)) * **jsii:** deduplicate interfaces ([#497](#497)) ([05f5189](05f5189)), closes [#496](#496) * **jsii-diff:** catch exception if type disappeared from other assembly ([#504](#504)) ([8d11900](8d11900)) * **jsii-diff:** correctly handle assignability of type unions ([#500](#500)) ([04c061e](04c061e)) * **jsii-diff:** don't fail on new packages ([#502](#502)) ([d1d0633](d1d0633)) ### Features * **jsii:** protect against prohibited member names ([#506](#506)) ([2848f76](2848f76)) ### BREAKING CHANGES * **jsii:** The `equals` and `hashCode` method names may no longer be used on JSII classes and interfaces, due to their colliding with "special meaning" methods in other languages (Java, .NET, ...).
