re PR tree-optimization/61328 (valgrind finds problem in find_bswap_or_nop_1)

PR tree-optimization/61328
* tree-ssa-math-opts.c (init_symbolic_number): Extract symbolic number
initialization from find_bswap_or_nop_1.
(find_bswap_or_nop_1): Test return value of find_bswap_or_nop_1 stored
in source_expr2 before using the size value the function sets. Also
make use of init_symbolic_number () in both the old place and
find_bswap_or_nop_load () to avoid reading uninitialized memory when
doing recursion in the GIMPLE_BINARY_RHS case.
