[PATCH] Fix up value_format ICE for DWARF2_ADDR_SIZE < 4 targets (PR target/55194)

[Jakub Jelinek]

Hi!

Apparently some targets have DWARF2_ADDR_SIZE < 4, for dw_val_class_addr
when DW_FORM_addr can't be used value_format already handles
DWARF2_ADDR_SIZE 1, 2, 4 and 8, so I've committed this change as obvious.

        * dwarf2out.c (value_format) <case dw_val_class_high_pc>: Handle
        also DWARF2_ADDR_SIZE 1 and 2.
