This adds a mechanism for debuggers to safely inject calls to Go functions on amd64. Debuggers must participate in a protocol with the runtime, and need to know how to lay out a call frame, but the runtime support takes care of the details of handling live pointers in registers, stack growth, and detecting the trickier conditions when it is unsafe to inject a user function call. Fixes #21678. Updates derekparker/delve#119.
