re PR c++/7503 ((x < Y ? X : Y) used for assignment causes wrong code)
PR c++/7503
* tree.c (lvalue_p_1): Disallow MIN_EXPR and MAX_EXPR as lvalues
if either operand has side-effects.
* typeck.c (rationalize_conditional_expr): Assert that neither
operand of MIN_EXPR or MAX_EXPR has side-effects.
(build_modify_expr): Add support for MIN_EXPR and MAX_EXPR.
Check that the "lhs" is a valid lvalue, i.e. that neither operand
of a MIN_EXPR or MAX_EXPR has a side-effect.
* g++.dg/opt/pr7503-1.C: New testcase for COND_EXPR lvalues.
* g++.dg/opt/pr7503-2.C: New testcase for <? and >? lvalues.
* g++.dg/opt/pr7503-3.C: New testcase for invalid <? lvalue errors.
* g++.dg/opt/pr7503-4.C: New testcase for <?= and >?= assignments.
* g++.dg/opt/pr7503-5.C: New testcase for side-effects with <?=.
