SI-7006 Recognize more jump only blocks
During ASM code emission we would recognize a block that consisted of
ICode-only artifacts (ENTER_SCOPE, EXIT_SCOPE, and LOAD_EXCEPTION)
followed by a jump. But we weren't using the same logic to recognize
all jump-only blocks. So jump-elision wasn't removing them. And that
in fact was why the ASM code emission had to do its special case.
This commit makes all jump-only block recognition use the same logic:
a jump-only block is one that has 0 or more ICode-only instructions
followed by a JUMP. It does't necessarily have to start with a JUMP.
There's now a debugWarning if the old NOP emitting code is triggered and
test t6102 is enhanced to error if that warning occurs.
