CoreCLR Interpreter - diagnostics #112744

This issue tracks required work and progress for the diagnostics changes needed for supporting the CoreCLR interpreter.

M1

M2

• Update debugger related code in CoreCLR to support interpreter frames.
• SOS gcroot and dumpstackobjects commands work with interpreted frames
  • gcroot works except for a weirdness - it reports slots located at the interpreter stack as "caller.rax+offset". So this needs to be fixed.
  • dumpstackobjects also dumps all the objects, but the SP/REG column is not right
• SOS gcinfo command works with interpreted methods
• SOS dumpmd command shows address of IR for interpreted methods

M3

• Modify the SOS ehinfo command so that it works with interpreted methods - it turned out it just works
• Add support for disassembling IR byte code to SOS u command (nice to have)

M4

M5

• Wire debugger protocol handler in CoreCLR to the interpreter
