* Add yarp/yarp_compiler.c as stencil for compiling YARP
This commit adds yarp/yarp_compiler.c, and changes the sync script
to ensure that yarp/yarp_compiler.c will not get overwritten
* [Misc #119772] Create and expose RubyVM::InstructionSequence.compile_yarp
This commit creates the stencil for a compile_yarp function, which
we will continue to fill out. It allows us to check the output
of compiled YARP code against compiled code without using YARP.
