    Add context-sensitive field name completion to Ada parser

    This updates the Ada expression parser to implement context-sensitive
    field name completion.  This is PR ada/28727.

    This is somewhat complicated due to some choices in the Ada lexer --
    it chooses to represent a sequence of "."-separated identifiers as a
    single token, so the parser must partially recreate the completer's
    logic to find the completion word boundaries.

    Despite the minor warts in this patch, though, it is a decent
    improvement.  It's possible that the DWARF reader rewrite will help
    fix the package completion problem pointed out in this patch as well.
