Not all literals need to be moved in the presence of
--text-section-literals or --auto-litpools, but only those created by
.literal pseudo op or generated as a result of relaxation. Attempts to
move other literals may result in abnormal termination of the assembler
due to the following assertion failure:
Internal error in xg_find_litpool at gas/config/tc-xtensa.c:11209.
The same assertion may also be triggered by attempting to assign literal
pools to literals in .init and .fini sections; don't try to do that.

* config/tc-xtensa.c (xtensa_is_init_fini): New function.
(xtensa_move_literals): Only attempt to assign literal pool to
literals with tc_frag_data.is_literal mark and not in .init or
.fini sections.
Join nested 'if' conditions to simplify function structure.
(xtensa_switch_to_non_abs_literal_fragment): Use
xtensa_is_init_fini to test for .init/.fini sections.
