Class constructors multiversioning

Hey,

Function multiversioning doesn't support class constructors. Attempting to
compile the attached example results in:

clang++ test2.cpp                                   :(
test2.cpp:7:41: error: attribute 'target' multiversioned functions do not yet
      support constructors
    __attribute__ ((target("default"))) foo() {

The same example compiles fine in gcc.

Cheers,

Nick
