[gold patch] Add miscellaneous cleanups for Fission support

[Cary Coutant <ccoutant at google dot com>]

This patch adds a couple of miscellaneous minor changes for Fission
that I've had in my local branch: support in dwarf_reader.cc for new
DW_FORM codes, and a .gdb_index test for inline functions. (There's
also an update to a comment in object.cc -- I can separate that one if
you prefer.)

OK to commit?
