Teach FoldBitCast to be able to handle bitcasts from (e.g.) i128 -> <4 x float>.
...
This allows us to simplify this:
union vec2d {
double e[2];
double v __attribute__((vector_size(16)));
};
typedef union vec2d vec2d;
static vec2d a={{1,2}}, b={{3,4}};
vec2d foo () {
return (vec2d){ .v = a.v + b.v * (vec2d){{5,5}}.v };
}
down to:
define %0 @foo() nounwind ssp {
entry:
%mrv5 = insertvalue %0 undef, double 1.600000e+01, 0 ; <%0> [#uses=1]
%mrv6 = insertvalue %0 %mrv5, double 2.200000e+01, 1 ; <%0> [#uses=1]
ret %0 %mrv6
}
instead of:
define %0 @foo() nounwind ssp {
