[PowerPC] Support for Packed BCD conversion builtins (#142723)
Support the following packed BCD builtins for PowerPC.
  
```
__builtin_national2packed - Conversion of National format to Packed decimal format.
__builtin_packed2national - Conversion of Packed decimal format to national format.
__builtin_packed2zoned    - Conversion of Packed decimal format to Zoned decimal format.
__builtin_zoned2packed    - Conversion of Zoned decimal format to Packed decimal format.
```
### Prototypes: 
`vector unsigned char __builtin_national2packed(vector unsigned char a,
unsigned char b);`
`vector unsigned char __builtin_packed2zoned(vector unsigned char,
unsigned char);`
`vector unsigned char __builtin_zoned2packed(vector unsigned char,
unsigned char);`

The condition for the 2nd parameter is consistent over all the 3
prototypes (0 or 1 only).

`vector unsigned char __builtin_packed2national(vector unsigned char);`
