[PATCH] D10991: [LNT] Reduce I/O execution time for Polybench

[Lang Hames]

Hi Renato,

I'm seeing intermittent failures on some of our internal arm64 builders
that I think are related to this. For example, I'm seeing:

******************** TEST (simple) 'reg_detect' FAILED! ********************
Execution Context Diff:
/.../build/tools/fpcmp: files differ without tolerance allowance
******************** TEST (simple) 'reg_detect' ****************************


I ran "reg_detect" manually 10 times and grabbed the raw output, and I'm
seeing variation from run to run:

Any thoughts on what could be causing this?
