[PowerPC] Implement low-order Vector Multiply, Modulus and Divide Instructions
This patch aims to implement the low order vector multiply, divide and modulo
instructions available on Power10.
The patch involves legalizing the ISD nodes MUL, UDIV, SDIV, UREM and SREM for
v2i64 and v4i32 vector types in order to utilize the following instructions:
- Vector Multiply Low Doubleword: vmulld
- Vector Modulus Word/Doubleword: vmodsw, vmoduw, vmodsd, vmodud
- Vector Divide Word/Doubleword: vdivsw, vdivsd, vdivuw, vdivud
