Remove use of static C++ objects that are destroyed at exit time (destructors)

Conditionally have the DEFINE_STATIC_LOCAL workaround <rdar://problem/6354696>
(Codegen issue with C++ static reference in gcc build 5465) based upon the compiler
build versions. It will use the:
static T& = *new T;
style for all other compilers.

 // Use these to declare and define a static local variable (static T;) so that
 //  it is leaked so that its destructors are not called at exit. Using this
