cmd/compile: fix bug in logic for computing var abstract origins The DWARF inline info generation code was using file/line/column (from src.Pos) as a means of matching up pre- and post-optimization variable nodes. This turns out to be problematic since it looks as though distinct formals on the same line can be assigned the same column number. Work around this issue by adding variable names to the disambiguation code. Added a testpoint to the linker DWARF test that checks to make sure each abstract origin offset of distinct within a given DWARF DW_AT_inlined_routine body. Fixes #23020.
