Summary: Fixes http://llvm.org/bugs/show_bug.cgi?id=20016 reproducible on new lea-5.ll case. Also use RSP/RBP for x32 lea to save 1 byte used for 0x67 prefix in ESP/EBP case. Test Plan: lea tests modified to include x32/nacl and new test added Reviewers: nadav, dschuff, t.p.northover Subscribers: llvm-commits, zinovy.nis Differential Revision: http://reviews.llvm.org/D4929 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216065 91177308-0d34-0410-b5e6-96231b3b80d8
