[Object/invalid.test] - Convert Object/corrupt.test to YAML and merge the result into invalid.test

Object/corrupt.test has the same purpose as Object/invalid.test:
it tests the behavior on invalid inputs.

In this patch I converted it to YAML, merged into invalid.test, 
added comments and removed a few precompiled binaries.
