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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190634 91177308-0d34-0410-b5e6-96231b3b80d8 2013-09-12 22:02:31 +00:00			`; RUN: llvm-as < %s \| llvm-dis \| FileCheck %s`
