[Mesa-dev] [PATCH] glsl/linker: Fix out variables linking during single stage

[Vadym Shovkoplias]

Since out variables are copied from shader objects instruction
streams to linked shader instruction steam it should be cloned
at first to keep source instruction steam unaltered.

Fixes: 966a797e433 glsl/linker: Link all out vars from a shader
objects on a single stage
