[PATCH 1/1] tests/shader_runner: Report compilation errors on the block's starting line.

[Francisco Casas]

From: Francisco Casas

So, if there is an error or a trace on "[pixel shader]" or similar
blocks, they get reported in the line with the tag at the beginning of
the block and no on the line where the next block starts.
