[BOLT] Change .debug_line emission for non-simple functions

Summary:
We use a special routine to emit line info for functions that we do not
overwrite. The resulting DWARF was not quite efficient as we were
advancing addresses using a larger than needed opcodes. Since there were
only a few functions that we didn't emit/overwrite, it was not a big
issue.

However, in lite mode the majority of functions are not overwritten and
as a result, the inefficiency in debug line encoding got exposed and
binaries were getting larger than expected .debug_line sections.

Fix it by using more conventional line table opcodes for address
advancing.
