rG9eb0df3aa98e: [BOLT][DWARF] Fix handling of inlined subroutine with no output PC
Summary

Clang can generate DW_TAG_inlined_subroutine with low_pc 0. With split dwarf
this led to range offset being a negative number.

Why is this change needed?

The condition is always true here.

It's noop. If range is empty we will normalize to low_pc/high_pc.
In subsequent diffs I want to remove it completely.

Remove unnecessary check.

872

Do we expect such range to be ignored by DWARF consumers? Why not push {0, 0} or {0, 1} then?

Removed, but it proved useful. Added extra test that would trigger it.

I want to preserve as much of original as possible.
