GCN: Restore build with GCC 4.8
For example, for "g++-4.8 (Ubuntu 4.8.4-2ubuntu1~14.04.4) 4.8.4", the recent
commit r13-3220-g45381d6f9f4e7b5c7b062f5ad8cc9788091c2d07
"amdgcn: add multiple vector sizes" broke the build:

[...]/source-gcc/gcc/machmode.h:410:7: note: ‘scalar_int_mode’ is not literal because:

^
[...]/source-gcc/gcc/machmode.h:410:7: note: ‘scalar_int_mode’ is not an aggregate, does not have a trivial default constructor, and has no constexpr constructor that is not a copy or move constructor
[...]
Addressing this like simiar issues have been addressed in the past.

* config/gcn/gcn.cc (VnMODE): Use 'case E_QImode:' instead of
'case QImode:', etc.
