Hi,

Attached is a patch to remove two "if" statements that always trigger.

tree_if_convert_cond_expr receives a COND_EXPR as an argument.  Since
this COND_EXPR is a statement and not the one appearing as the rhs of
a MODIFY_EXPR, each arm of COND_EXPR always has a GOTO_EXPR.

In tree_if_convert_cond_expr's terms, then_clause and else_clause
always have GOTO_EXPR, so we don't need two "if" statements

Can you put gcc_asserts in their place please?
