* builtins.c (expand_builtin_int_interclass_roundingfn): New function
to handle optabs that operate on floating point input argument and
output to integer output.
(expand_builtin_mathfn) [BUILT_IN_ILOGB]: Move from here ...
(expand_builtin_interclass_mathfn) [BUILT_IN_ILOGB]: ... to here.
(expand_builtin): Expand BUILT_IN_ILOGB{,F,L} using
expand_builtin_interclass_mathfn ().
* config/i386/i386.md (fxtractxf3_i387): Rename from *fxtractxf3_i387.
(ilogbsi2): Remove.
(ilogbxf2, ilogb<mode>2): New expanders to implement ilogb, ilogbf and
ilogbl built-in functions as x87 intrinsics.
