Walfred Tedeschi 5230b05a94 dwarf2read: Restrict ICC workaround to ICC<14 
GDB has a workaround for DWARF output by ICC, related to missing
DW_AT_declaration on incomplete types.  The bug was fixed in ICC 14,
so this commit adjusts GDB accordingly.

For the version check, this adds a new parser function for the ICC
producer string.  While at it, it also adds unit tests for the
producer parsing covering the new function and preexisting parsers.
