Lowering Compilation Threshold in C2 for specific methods

         Is there currently a way to change the compilation threshold on 
a per method basis for C2? I am asking this question in the context of 
intrinsics, since instead of adding interp/C1 support for an intrinsic, 
there should be a way to just always use the C2 version of the method. 
Methods like CRC32 that have interp, C1, and C2 hooks that always call 
into the intrinsics if they are available, should have a mechanism for 
only providing a C2 intrinsic and changing the threshold so that C2 code 
is always used, seems like a much cleaner approach.
