SPARC: jmpl and return in user trap handler

[mumbel]

Describe the bug
jmpl and return are both delayed execution instructions; however, they are an instruction group used in user trap handlers. See A.45 RETURN programming note ex:

jmpl %16,%g0
return %17

Just running into this with disassembly, not sure what the sleigh would need to do, just causes a lot of un-disassembled code and error bookmarks.

Environment (please complete the following information):

• OS: win10
• Java Version: 17.0.5
• Ghidra Version: 11.0
• Ghidra Origin: official
