Remove I8/I16 register classes which are prepared to implement previously
to implement VE ABI. However, it is possible to implement VE ABI correctly
without them. Therefore, removing them now.

VE has only 64 bits AND/OR/XOR instructions. We pretended that VE has 32 bits
instructions also, but doing it increase the number of generated instructions.
Therefore, we decide to promote 32 bits operations and use only 64 bits
instructions in back end. We also avoid pretending that VE has 32 bits LEA
instruction. Update regression tests also.

Change to expand MULHU/MULHS/UMUL_LOHI/SMUL_LOHI for i32 and i64 since
those instructions are not available on Aurora SX VE. Some of them
are used in expansion of i128 multiply, so need to modify them to
