Hi!
The following testcase ICEs in C, because assume attribute condition
has int type rather than bool and the gimplification into GIMPLE_ASSUME
assigns it into a bool variable.
Fixed by calling gimple_boolify.
Bootstrapped/regtested on x86_64-linux and i686-linux, committed to trunk.

* gimplify.cc (gimplify_call_expr): For complex IFN_ASSUME
conditions call gimple_boolify on the condition.
