Bug 216718: multimedia/ffmpeg: clang 4.0 crashes with -O3 -march=native

--- Description ---
ffmpeg already passes -O3 by default as part of OPTIMIZED_CFLAGS option, so
only CPUTYPE?=native in make.conf was something new.

Assertion failed: (isLoopInvariant(Operands[i], L) && "SCEVAddRecExpr operand
is not loop-invariant!"), function getAddRecExpr, file
/usr/src/contrib/llvm/lib/Analysis/ScalarEvolution.cpp, line 2963.
