This Go frontend patch by Cherry Zhang avoids a copy for a
string([]byte) conversion used in a string comparison. If a
string([]byte) conversion is used immediately in a string comparison,
we don't need to copy the backing store of the byte slice, as the
string comparison doesn't hold any referenc

Hi,
This patch adds a pattern to support the FADDP (scalar) instruction.
Before the patch, the C code
typedef double v2df __attribute__((vector_size (16)));
double
foo (v2df x)
{
return x[1] + x[0];
}
generated:
foo:
dup d1, v0.d[0]
dup d0, v0.d[1]
