v3_kernel: Clean up handling of guards

Handling of guards become a mess when andalso/orelse in guards
were introduced. Clean it up by using common code for most
constructs, regardless of where they occur, and when needed use
is_in_guard/1 to handle guard constructs differently.
v3_kernel: Dig out the line number only when generating a warning
v3_core: Don't put negative line numbers in annotations

In Core Erlang and later passes, compiler-generated code can be
indicated in two different ways: by negative line numbers and by
a 'compiler_generated' annotation.

Simplify the code and improve coverage by turning negative line
numbers positive and adding a 'compiler_generated' annotation in
the v3_core pass. That means that Core Erlang and latter passes
do not have deal with negative line numbers.
