Add PetscFPTrapPush() and PetscFPTrapPop(), use to guard LAPACK calls that set floating point exceptions

ieeeck() intentionally creates exceptions to find out whether they
trap. The call graph with some LAPACK implementations is
dgesvd() -> dbdsqr() -> dlasq1() -> dlasq2() -> ilaenv() -> ieeeck()
so the eigenvalue routines fail when trapping is set.
