Fix PR65261
Running bootstrap-ubsan on ppc64le shows many instances of:
libcpp/lex.c:552:30: runtime error: load of misaligned address
0x01001f31d37a for type 'const uchar', which requires 16 byte alignment
But the unaligned vector loads are intended in this case, because they
are preferable to forced-alignment on POWER8. So just silence the ubsan
errors.
