Fix a bug in the type-legalization of vector integers. When we bitcast one vector type to another, we must not bitcast the result if one type is widened while the other is promoted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148383 91177308-0d34-0410-b5e6-96231b3b80d8 2012-01-18 08:33:18 +00:00			`; RUN: llc < %s -march=x86-64 -mcpu=corei7 -mtriple=x86_64-pc-win32 \| FileCheck %s`
