x86: Prepare asm files for straight-line-speculation
[ Upstream commit f94909ceb1ed4bfdb2ada72f93236305e6d6951f ]
Replace all ret/retq instructions with RET in preparation of making
RET a macro. Since AS is case insensitive it's a big no-op without
RET defined.

do
sed -i 's/\<ret[q]*\>/RET/' $file
done
