Details

With VFP enabled, D0-D7 are not callee-saved (scratch); D8-D15 are. The current ARM code is confused, and has D0-D7 in SavedFpRegs which might cause them to be clobbered by functions that are called. We don't use D8-D15 at all, so SavedFpRegs must be 0 everywhere.
Obsolete with the removal of tracejit.
