4.4 API changes

[Jamie Prescott]

I managed to migrate my code to 4.4, but I've some code I cannot figure out
how to translate.
Before, I was building the TRUE and FALSE  instruction list using gimplify_and_add(),
and then a:

build3(COND_EXPR, void_type_node, cond, a_case, b_case);

Where 'a_case' and 'b_case' were tree's.
Now I build two gimple_seq's in the same way, but I cannot see how to pass them to build3().
Is there an API to get the first tree out of the gimple_seq? Or, is there a build3() equivalent
that accepts gimple_seq's?
