Support f128 using VE instructions. Update regression tests.
I've noticed there is no load or store i128 test, so I add them too.

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 bitreverse/bswap/ctlz/ctpop/cttz regression tests to support i128
and signext/zeroext i32 types. This patch also change the way to support
i32 types using 64 bits VE instructions.

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
support i128. Then, update basic arithmetic regression tests of
i128 and signed/unsigned i32 typed integer values.

Change to not generate truncate instructions if all use of a truncate
operation don't care about higher bits. For example, an i32 add
instruction doesn't care about higher 32 bits in 64 bit registers.
