[PATCH] rs6000: Support more short/char to float conversion

Hi, For some cases that when we load unsigned char/short values from the appropriate unsigned char/short memories and convert them to double/single precision floating point value, there would be implicit conversions to int first. It makes GCC not leverage the P9 instructions lxsibzx/lxsihzx. Thi
