  Log Message:
  -----------
  [GlobalISel] Remove debug locations when emitting constants.

The tl;dr story is that this causes jumps in the emitted line
tables, even at `-O0`. We could at some point consider more fancy
solutions to preserve locations, but it doesn't seem to be worth
the effort for now.
