Enhance type legalization on bitcast from vector to integer - Find a legal vector type before casting and extracting element from it. - As the new vector type may have more than 2 elements, build the final hi/lo pair by BFS pairing them from bottom to top. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163830 91177308-0d34-0410-b5e6-96231b3b80d8 2012-09-13 19:58:21 +00:00			`; RUN: llc -mtriple=x86_64-unknown-unknown -mcpu=core-avx-i < %s \| FileCheck %s --check-prefix CHECK`
