[PATCH] D67678: PR17164: Change clang's default behavior from -flax-vector-conversions=all to -flax-vector-conversions=integer.

For ARM compilations with NEON enabled, for now we retain the old
default of -flax-vector-conversions=all, because our intrinsic header
<arm_neon.h> relies on it, and it appears to be far from straightforward
to fix that. (See PR43341.)
