<span class="quote">> Tested latest Mesa. On my SKL GT2 the slow shader still takes ~20s to

Latest Mesa (i.e. 5 months later) uses 17-18ms to compile on that machine, and
gets following statistics:
SIMD8 shader: 8127 instructions. 0 loops. 57436 cycles. 369:1019 spills:fills.
Promoted 18 constants. Compacted 130032 to 87472 bytes (33%)
I.e. there's been a minor improvement in compile time, but regression from
v11.2 is still valid and spilling & instruction counts have gotten slightly
worse. "perf" output looks same as earlier.</pre>
