gas: xtensa: merge trampoline_frag into xtensa_frag_type
The split between fragS and trampoline_frag doesn't save much space, but
makes trampolines management much more awkward. Merge trampoline_frag
data into the xtensa_frag_type, which is a part of fragS. No functional
changes.

* config/tc-xtensa.c (init_trampoline_frag): Replace pointer to
struct trampoline_frag parameter with pointer to fragS.
(xg_append_jump): Remove jump_around parameter.
(struct trampoline_frag): Remove.
(struct trampoline_seg): Change type of trampoline_list from
struct trampoline_frag to fragS.
(xtensa_create_trampoline_frag): Don't allocate struct
trampoline_frag. Initialize new fragS::tc_frag_data fields.
(dump_trampolines, xg_relax_trampoline, search_trampolines)
(get_best_trampoline, init_trampoline_frag)
(add_jump_to_trampoline, relax_frag_immed): Replace pointer to
struct trampoline_frag with a pointer to fragS.
(xg_append_jump): Remove jump_around parameter, use
fragS::tc_frag_data.jump_around_fix instead.
(xg_relax_trampoline, init_trampoline_frag)
(add_jump_to_trampoline): Don't pass jump_around parameter to
xg_append_jump.
* config/tc-xtensa.h (struct xtensa_frag_type): Add new fields:
needs_jump_around, next_trampoline and jump_around_fix.
