Fixed by r11-1571 and r10-8343: Refinements to "more constrained".

Jason, was the change to tsubst_pack_expansion a drive-by fix that resolved
this bug?

* pt.c (tsubst_pack_expansion): Fix getting a type parameter
pack.


The rest of the commit is related to constrained functions, which aren't
relevant here.

Should we add this testcase before closing the bug?

There is a simpler case.

test.cpp:
template 
void foo(T2, Types...)
{
}

template 
void foo(int, Types...)
{
}

int main()
{
  foo(1, 2);
}

Command line:
g++ -std=c++11 test.cpp -o test

Output:
test.cpp: In function ‘int main()’:
test.cpp:13:17: error: call of overloaded ‘foo(int, int)’ is ambiguous
   foo(1, 2);
 ^
test.cpp:13:17: note: candidates are:
test.cpp:2:6: note: void foo(T2, Types ...) [with T1 = void; T2 = int; Types =
{int}]
 void foo(T2, Types...)
  ^
test.cpp:7:6: note: void foo(int, Types ...) [with T1 = void; Types = {int}]
 void foo(int, Types...)

I tried this with versions 4.8.1, 4.9.1, 4.9.2 - same result.
Clang has no problems with this code.
