Log Message
Unreviewed build fix for GCC 4.9 builds.
* assembler/MacroAssemblerCodeRef.h: std::is_trivially_copyable<> isn't
supported in 4.9 libstdc++, so wrap the static assert using it in a
COMPILER_SUPPORTS() macro, and use __is_trivially_copyable() builtin,
as is done in bitwise_cast() in StdLibExtras.h.
