I've done that now running the gpu profile with clean upstream
(f623e1742f) and my patches on top (twice each time). The only
consistent change is fixing  

   vs-output-array-vec2-index-wr-before-gs 

A bit strange is spec/arb_sync/repeate_wait because it is skipped once
with clean upstream but passes otherwise.

spec/nv_conditional_render failed once with my patch applied, but it
doesn't do any register merging and when I run the test from the
command line it always passes (also when explicitly cleaning the shader
cache). I didn't try running it with a clean upstream more then twice
though. 

All other changes versus a clean upstream are non-deterministic, i.e.
fail and pass once for each code version. 

In detail these are 

glx/
  - glx_arb_sync_control (all timing-* tests)

  - security
      initialized-fbo       (warn/pass)
      initialized-texmemory (warn/pass), 

spec/
  - arb_tessellation_shader
     tcs-input-read-array-interface
     tcs-input-read-mat
     tcs-input-read-nonconst-interface-builtin

Best, 
Gert
