[SPARC] Use adjust_address instead of adjust_address_nv in sparc.md

- Authentication-results: sourceware.org; auth=none
3 patterns related to setjmp/longjmp/non-local gotos call adjust_address_nv
and this can break (generate unrecognizable insns) when things get serious,
for example if you configure with --enable-sjlj-exceptions.
Tested on SPARC/Solaris, applied on the mainline.

* config/sparc/sparc.md (save_stack_nonlocal): Use adjust_address
instead of adjust_address_nv.
(restore_stack_nonlocal): Likewise.
(nonlocal_goto): Likewise.
