[ARC]PR 88409: miscompilation due to missing cc clobber in longlong.h macros
simple test such as below was failing.
| void main(int argc, char *argv[])
| {
| size_t total_time = 115424; // expected 115.424
| double secs = (double)total_time/(double)1000;
| printf("%s %d %lf\n", "secs", total_time, secs); // prints 113.504
| printf("%d\n", (size_t)secs);
| }
The printf eventually called into glibc stdlib/divrem.c:__mpn_divrem()
which uses the __arc__ specific inline asm macros from longlong.h which
were causing miscompilation.
