Torture does not change the rounding modes (I believe it uses round-nearest-even).
Torture does not test statically-specified rounding modes.

My goal is for torture to be able to catch a bug like this (https://github.com/ucb-bar/rocket/commit/d4ead08579fe9d8cfa9468b0949393401770ce46), in which the Fdiv/sqrt unit was using the wrong pipeline stage's rounding mode for performing DP->SP conversions of the output.
