ppc-aix osabi sniffer: Turn test of bfd flavour into assertion

Due to the way this function is registers, we know that given bfd's
flavour should always be bfd_target_xcoff_flavour, thus making
the former test always true, which means that this function should
always return GDB_OSABI_AIX, and never return GDB_OSABI_UNKNOWN.

This patch also fixes a typo detected by Tom Tromey that caused
the test itself to be completely ineffective.

gdb/ChangeLog (by Tom Tromey and Joel Brobecker):

        * rs6000-aix-tdep.c (rs6000_aix_osabi_sniffer): Replace
        inneffective if condition by gdb assertion.  Add function
        description comment.

Document exp_descriptor.op_name should never return NULL.

This documents a constaint that struct exp_descriptor's "op_name"
method implementation should obey.  This might not have been part
of the initial design, but is currently true of all instantiations,
and already assumed by the current users.

gdb/ChangeLog:

        * parser-defs.h (struct exp_descriptor): Document constraint
        on return value for "op_name" callbacks.

* compress.c: Revert previous patch.

* compress.c (bfd_get_full_section_contents): Don't cache
decompressed contents.

    * gdb.base/ctxobj.exp: Skip if skip_shlib_tests returns true.
