+++ This bug was initially created as a clone of Bug #976624 +++
Description of problem:
Some libm functions implement only rounding to nearest, so to ensure correctness they set and restore the default rounding mode. This is unnecessary in the default case and is hence a performance impediment. Upstream has solved this by calling the set/restore code only when the current rounding mode is not the default. Backport that fix.
