glsl: Properly handle blocks that define the same field name.
Currently we can have name space collisions between blocks that define the same
fields. For example:
in block
{
vec4 Color;
} In[];
out block
{
vec4 Color;
} Out;
These two blocks will assign the same interface name (block.Color) to the Color
field in flatten_named_interface_blocks_declarations.cpp, leading to havoc.
This was breaking badly the gl-320-primitive-shading test from ogl-samples.
The patch uses the block instance name to avoid collisions, producing names
like block.In.Color and block.Out.Color to avoid the name clash.
