<pre>The C API does not allow to control the threshold value that was added with
<a href="https://reviews.llvm.org/D71673">https://reviews.llvm.org/D71673</a>. For example in pass_manager_builder.h it would
be nice to have `LLVMPassManagerBuilderSetInstCombineThresh`.
Then, the default value for the default set of passes, e.g the set that is
initialized when we use `LLVMPassManagerBuilderPopulateFunctionPassManager`, is
not equal to the value used by opt and infinite loops are still possible.
The request here is to have at least a default value that protect against those
infinite loops.
The consequence is that compilers that use the C API have to optimize by
invoking opt.</pre>
