re PR middle-end/18548 (Miscompiles code generated by Gambit-C Scheme->C compiler)

PR middle-end/18548
* expr.c (expand_expr_real_1) <MAX_EXPR>: Ensure that target, op0
and op1 are all registers (or constants) before expanding the RTL
comparison sequence [to avoid reg_overlap_mentioned (target, op1)].

* gcc.dg/max-1.c: New test case.
