Workaround for GCC internal compiler error.
GCC 4.8.0 generates internal compiler error (assign_by_spills) in
RandomArrayGenerator::createQuads() when compiled with -march=prescott.
As a workaround for the error, disable inlining of
alignmentSafeAssignment() when compiling for x86 using the affected GCC
version.
