re PR rtl-optimization/49472 (Compiler segfault on valid code)
PR rtl-optimization/49472
* simplify-rtx.c (simplify_unary_operation_1) <case NEG>: When
negating MULT, negate the second operand instead of first.
(simplify_binary_operation_1) <case MULT>: If one operand is
a NEG and the other is MULT, don't attempt to optimize by
negation of the MULT operand if it only moves the NEG operation
around.
* gfortran.dg/pr49472.f90: New test.
