 Log Message:
 Resurrect silently removed lines in rev 1.37 that update FPU_CSR
 in double's inexact or overflow cases.
 
 Now the following tests are passed:
 ---
 tp-start: t_except, 6
 tc-start: masked_double
 tc-end: masked_double, passed
  :
 tc-start: masked_long_double
 tc-end: masked_long_double, passed
  :
 tp-start: t_subnormal, 2
 tc-start: test_double
 tc-end: test_double, passed
 ---
 
 The following ones still fail:
 ---
 tp-start: t_except, 6
  :
 tc-start: unmasked_double
 tc-se:*** Check failed: /usr/src/tests/lib/libc/ieeefp/t_except.c:269: sicode

 tp-end: t_except

 tp-end: t_subnormal

 - t_except unmasked failures are mentioned in PR port-mips/35327.
 - t_subnormal float failure seems trap caused by a FP insn in BDslot
   (I'm not sure if we can use TF_REG_CAUSE in trapframe to see BD bit)
