[SelectionDAG] Fixed issue with uitofp vector constant folding being treated as sitofp
While the uitofp scalar constant folding treats an integer as an unsigned value (from lang ref):
%X = sitofp i8 -1 to double ; yields double:-1.0
%Y = uitofp i8 -1 to double ; yields double:255.0
The vector constant folding was always using sitofp:
%X = sitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0>
%Y = uitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0>
This patch fixes this so that the correct opcode is used for sitofp and uitofp.
%X = sitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0>
%Y = uitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double 255.0, double 255.0>
