New Revision: 160543

URL: http://llvm.org/viewvc/llvm-project?rev=160543&view=rev
Log:
Don't use implicit register operands to calculate L-bit for AVX instructions. Needed because super reg defs and kills are added as implicit operands on 128-bit instructions. Fixes PR13349. Patch by Jose Fonseca.
