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 2013-09-13 06:02:31 +08:00			`; RUN: llvm-as < %s \| llvm-dis \| FileCheck %s`
