[Revise prev change -- this is how it's been running at Adobe, and it works
 there.]

* sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
coprocessor status regs) when popping a frame.  This fixes
float exceptions that occur after calling inferior functions.

* sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
Read and write the fsr (float status register) to/from the child
process along with the float regs.  Remove Peter Schauer's change
of May 24 '93, which has higher overhead and doesn't solve the
real problem (which was that FSR wasn't being set).
