[Bug debug/43442] New: .debug_loc is unnecessarily large

["jakub at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

While looking at PR43058, I've noticed that we generate tons of completely
useless location list elements.  E.g. on the pr43058.c testcase with X2 instead
of X4 X4 and without the PR43058 patch applied, we generate extremely long
location list for the first a variable and then each loclist is 2 entries
shorter.  Most of the ranges in the list don't overlap with any DW_AT_ranges
in the containing DW_TAG_lexical_block though.
