SPIRV-Cross->HLSL: undeclared identifier

[Jack-Clark]

I think I have found another undeclared identifier issue in SPIRV-Cross. I'm using the latest commit, so the previous fix has been applied, yet I still get undeclared identifier errors when converting to HLSL.

Here is a fragment of the HLSL output that is causing the issue:

for (;;)
{
    _22.Store(_200 * 4 + 0, 23u);
    uint _203 = _200 + 1u;
    break;
}
uint _213;
uint _214;
uint _230;
uint _231;
uint _238;
uint _239;
uint _205 = _203;

I presume in HLSL, normal scoping rules apply, so the uint _203 = _200 + 1u definition is not visible to the uint _205 = _203 line? _205 is not declared anywhere else above this.
