compiler: improve debugging experience
...
Currently one instruction can correspond to multiple sequence points
because of inlining. This leads to a bad user experience as only
the last one is used. In this commit we create a sequence point for each
inlined call and also make sure that each time a new sequence point is
created the corresponding opcode can easily be seen in code.
The NOPs increase contract size, but not to a large degree. Other
solutions considered:
1. Discard NOPs if a special flag is provided. Still leads to bad
debugging experience if deployed contract differs from the debugged
one.
2. Create an issue for a debugger. When multiple sequence points are
provided for a single instruction they can be used to emulate
non-inline behaviour with pseudo-NOPs. I believe this is what windows
debugger does (the last paragraph https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/debugging-optimized-code-and-inline-functions-external )
3. Emit debug info for inlined functions even without creating a
function in the NEF itself. This should be done for each called
instance and would also create overlapping opcode ranges for
the enclosing function. However this approach can also ensure
consistent values view for inlined function parameters.

compiler: use absolute paths for debug data
...
It's not a perfect thing, but neo-debugger just doesn't work at all with
relative pathes. Notice that `saveSequencePoint` still used absolute ones
leading to invalid debug.json data, but fixing it there doesn't help,
neo-debugger can't load source code using relatives.
