[Piglit] [PATCH 3/6] sso: new test IsProgramPipeline:

[Gregory Hainaut]

check the Pipeline object state creation. GenPipeline
only reserved name. I also take the opportunity to test negative value
on glGenProgramPipelines and glDeleteProgramPipelines.
Note: FGLRX don't follow the spec besides crash on glGenProgramPipelines because of -1...
Note: Nvidia crash on glGetProgramPipelineiv(id[3], GL_VERTEX_SHADER, &dummy), no shader
was set to they probably unreference a NULL pointer. By the way Nvidia doesn't follow the
spec neither.

V4: split the new test in a separate commit
