There are CPU bugs^Wfeatures that can have interesting effects if RIP is non-canonical. I didn't make the corresponding x86_32 change, since x86_32 has no concept of canonical addresses. putreg32 doesn't need this fix: value is only 32 bits, so it can't be non-canonical. Fixes CVE-2014-4699. There are arguably still bugs here, but this fixes the major issue.
