Fix test case for PR117811 which failed for int < 32 bit.

caused

FAIL: c-c++-common/tsan/tls_race.c   -O0  output pattern test
FAIL: c-c++-common/tsan/tls_race.c   -O2  output pattern test

with GCC configured with

../../gcc/configure

To reproduce:

$ cd {build_dir}/gcc && make check 
RUNTESTFLAGS="tsan.exp=c-c++-common/tsan/tls_race.c --target_board='unix{-m64\ 
-march=cascadelake}'"

(Please do not reply to this email, for question about this report, contact me 
at haochen dot jiang at intel.com.)
(If you met problems with cascadelake related, disabling AVX512F in command 
line might save that.)
(However, please make sure that there is no potential problems with AVX512.)
