At one point -flax-vector-conversions was default and did the option did not
exist.

NOTE having this option on is required to be complaint with both the Altivec
and SPU PEMs.  I remember when this discussion was happening since I was
working on PowerPC and I even voted against having an option to allowing the
lax conversion part.
