middle-end/102129 - avoid TER of possibly trapping expressions

The following avoids applying TER to possibly trapping expressions,
preventing a trapping FP multiplication to be moved across a call
that should not be executed.

* tree-ssa-ter.c (find_replaceable_in_bb): Do not move
possibly trapping expressions across calls.
