Reduced gcc.dg/torture/builtin-math-3.c
The two lines causing link_error() to be called as in the linker error messages
are cut out and the condition is reduced such that the emitted assembly-code is
still identical. Compile with e.g. -O1. Observe libcalls for "<=" and ">="
being called for constants, while in the pre-regression code, everything is
optimized out to the effect of "return 0;"
