gimplify: Call gimple_boolify on IFN_ASSUME argument [PR107368]
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.

* gimplify.cc (gimplify_call_expr): For complex IFN_ASSUME
conditions call gimple_boolify on the condition.
* gcc.dg/attr-assume-5.c: New test.
