Patch provide by Tom Roeder! Reviewed by Joe Abbey and Tobias Grosser Here is a patch that fixes decoding of CE_SELECT in BitcodeReader, along with a simple test case. The problem in the current code is that it generates but doesn't accept bitcode that uses vectors for the first element of a select in this context. llvm-svn: 190634

[BitcodeReader] Ensure we can read constant vector selects with an i1 condition Summary: Constant vectors weren't allowed to have an i1 condition in the BitcodeReader. Make sure we have the same restrictions that are documented, not more.
