Fix function argument and return value locations

For function arguments (callfuncs.exp), only TYPE_CODE_COMPLEX was
missing in the types passed via integer registers.
For return values, there were a lot more issues:
- TYPE_CODE_DECFLOAT is NOT returned via XMM0.
- long double is NOT returned via XMM0.
- but __int128 IS returned via XMM0.
- the comments for TYPE_CODE_FLT state that __m128, __m128i and __m128d are
returned by XMM0, and this is correct, but it doesn't actually check for
them, because they are TYPE_CODE_ARRAY with TYPE_VECTOR
So I had to add TYPE_CODE_DECFLOAT to the arguments passed via XMM register,
but I had to remove it from the values returned via XMM0 register.
gdb/ChangeLog:
2020-10-05 Hannes Domani <ssbssa@yahoo.de>
* amd64-windows-tdep.c (amd64_windows_passed_by_integer_register):
Add TYPE_CODE_COMPLEX.
(amd64_windows_return_value): Fix types returned via XMM0.
gdb/testsuite/ChangeLog:
2020-10-05 Hannes Domani <ssbssa@yahoo.de>
* gdb.base/call-sc.c: Fix return struct on stack test case.
* gdb.base/call-sc.exp: Likewise.
