    dwarf2out: Emit DW_AT_location for global register vars during early dwarf
[PR101905]

    The following patch emits DW_AT_location for global register variables
    already during early dwarf, since usually late_global_decl hook isn't even
    called for those, as nothing needs to be emitted for them.

            * dwarf2out.c (gen_variable_die): Add DW_AT_location for global
            register variables already during early_dwarf if possible.

            * gcc.dg/guality/pr101905.c: New test.
