commit e7668c50a5c0b069669e40159089dbb60db8392c

Enhance vec_extract from int memory with constant element numbers.
This patch adds a combine insn that merges loading up a vec_extract of V4SFmode
where the element number is constant combined with a conversion to DFmode.
Without this patch, the compiler would load the value into a GPR register and
then do a direct move if it needs the value in a vector register.
