Do not check whether memory references accessed in every iteration trap.

This patch relaxes the checks from gimple_could_trap_p in order to
allow the flag_loop_if_convert_stores to if-convert more loops
in which it is possible to prove that:

- the accesses to an array in a loop do not trap (more than the
  original non-if-converted loop).  This is true when the memory
  accesses are executed at every iteration of the if-converted loop.

- the writes to memory occur on arrays that are not const qualified.
  This is true when there exists at least one unconditional write to
  the array in the analyzed program.  In this patch this analysis is
