[PATCH] Added noexcept on constructors

[Aditya Kumar]

Since g++ correctly finds this error, I'm wondering how
libstdc++-v3/src/c++11/shared_ptr.cc was compiling correctly before.

With a small test case:
$ cat tes.cpp
class A {
  public:
  A() noexcept;
};

A::A() {
}

$ ../../build/gcc/xg++ -B ../../build/gcc -c test.cpp -std=gnu++14

test.cpp:6:1: error: declaration of 'A::A()' has a different exception
specifier
 A::A() {
 ^
test.cpp:3:3: note: from previous declaration 'A::A() noexcept'
   A() noexcept;

Thanks,
-Aditya

Thanks for the patch (and thanks, Ville, for reviewing it).

I'll commit this today.
