* src/mcs51/gen.c (genFunction, genEndFunction),
* src/ds390/gen.c (genFunction, genEndFunction): Moved save
and restore of EA so that stack offsets to parameters are
correct when using both critical and reentrant/stack-auto.

size (can be triggered in error if sloc is shared between
different sized objects)
