        src/lib/libc/arch/sparc64/gen: longjmp.c setjmp.S sigsetjmp.S

Log Message:
Fix offsets used in the assembly code to save global registers into a
jmp_buf, add a compile time assert to catch this kind of divergence
in the C code.
Move the fixed "%npc = %pc + 4" computation to longjmp, this frees
the sigcontext sc_npc value. Use this space to save the savemask
for siglongjmp (we have run out of space behind the globals).
Fixes the tests/lib/libc/setjmp/t_threadjmp tests, and also hopefully
fixes PR port-sparc64/44902.
