piglit test that triggers the faulty behaviour

The attached piglit test will run through in release mode, because sb bails out
in the post_scheduler: 

##post_scheduler: unscheduled pending instructions :MOV     R6.x.1F,   
0.5|3f000000
MOV     R5.x.1F,    0|00000000
MOV     R3.x.1F,    1|3f800000
sb: error (1) in the post_scheduler pass.
sb: using unoptimized bytecode...

Obviously it would be preferable if sb would generate proper code instead.
Also in debug mode an assertion will fail at this point.

It is another incarnation of #103142, but I think it is better to open this as
a new bug.</pre>
