libsanitizer: Use SSE to save and restore XMM registers
Use SSE, instead of AVX, to save and restore XMM registers to support
processors without AVX. The affected codes are unused in upstream since
https://github.com/llvm/llvm-project/commit/66d4ce7e26a5
and will be removed in
https://reviews.llvm.org/D112604
This fixed
FAIL: g++.dg/tsan/pthread_cond_clockwait.C -O0 execution test
FAIL: g++.dg/tsan/pthread_cond_clockwait.C -O2 execution test
on machines without AVX.

* tsan/tsan_rtl_amd64.S (__tsan_trace_switch_thunk): Replace
vmovdqu with movdqu.
(__tsan_report_race_thunk): Likewise.
