Commit Message

TARGET_FPRND should be on for everything ISA 2.04 and later, and
TARGET_VSX implies ISA 2.06 or later; but it is possible to disable
TARGET_FPRND (separately via -mno-fprnd, but also implicitly)
currently, and then things fall down.  This patch makes things not
fall down.

Committing to trunk, and queued up for backports.
